Chapter 21
On What Eternity Is, and Why It Gives God Room to Work
Suppose heaven is a single frozen instant. No before. No after. No sequence at all. Just one timeless "now" that never moves.
If that is what eternity means, then the long healing we described in Chapter 20 has nowhere to happen. Growth requires a next step. Change requires a before and an after. A person who is slowly, freely turning from rebellion to trust needs time to turn in. If eternity is a place without time, then there is no room for the patient work of a God who will not force but who will not stop.1
And yet the whole case I have been building rests on a quiet assumption: that there is time after death. Not just a little time. Endless time. Time enough for every appeal, every encounter, every whispered invitation. Time enough for the hardest heart to soften. I argued in Chapter 17 that nobody can refuse God forever once they see Him clearly. I argued in Chapter 19 that death does not cut off grace. I argued in Chapter 20 that personal transformation across ages is real and coherent. But all of those arguments lean on the same unstated premise: that eternity has real duration. That it offers a genuine "after."2
So before I close Part Five, I need to examine that premise directly. What is eternity? Is it timeless or temporal? Does the afterlife include real moments, real sequence, and real room for change? Or is it a frozen picture in which nothing ever moves?
The answer to this question decides whether the rest of the case can stand.
This is not just a puzzle for philosophers. It touches what every believer imagines when they think about heaven.
When a Christian pictures the life to come, she usually pictures something that unfolds. She pictures worship, conversation, reunion, exploration, growth in the knowledge of God. She pictures the tree of life "yielding its fruit each month" (Revelation 22:2). She pictures a story that keeps going, not a snapshot. And that picture requires time. Without sequence, there is no unfolding. Without duration, there is no "each month." Without a real "next," there is no ongoing fellowship with God or with other persons.3
For the case I have been making, the stakes are even higher. If the afterlife has no real duration, then three load-bearing arguments collapse at once.
First, the argument from Chapter 17: that no one can hold out against God forever. "Forever" assumes time. If there is no time after death, there is no "holding out," and no moment at which resistance gives way. The infinite-opportunity argument needs infinite opportunities, and those require real, successive moments.4
Second, the argument from Chapter 20: that moral transformation across the ages preserves personal identity. "Across the ages" is a temporal claim. If the eschaton is a timeless instant, the gradual healing of a sinful person into a saint has no room to proceed. There is no journey if there is no road.
Third, the argument from Chapter 15: that God saves without forcing, using perfectly fitted appeals to each person. Those appeals take place in encounters, in moments, in a real sequence of invitations. They need time. Without it, optimal grace collapses into something instantaneous and totalizing, which is exactly the kind of force this book rejects.5
Plain Words
Several technical terms will appear in this chapter. Presentism is the view that only the present moment of time exists; the past is gone and the future has not yet arrived. Eternalism (sometimes called the "block universe") is the view that all moments of time, past, present, and future, are equally real. Divine temporality is the view that God experiences real sequence, a genuine before and after, rather than existing in a single timeless instant. A-theory holds that the flow of time is real; B-theory holds that all moments simply exist in fixed order without any objective "now." This chapter argues that the first and third of these best serve the standard Christian story.
So the question is not academic. It is structural. The answer to "what is eternity?" either gives the larger hope the stage it needs or takes the stage away.
When Christians say "eternal life," they can mean two very different things. These two pictures have lived side by side in the tradition for centuries, and telling them apart is the first step.
The first picture is timelessness. On this view, God exists outside of time altogether. He does not experience a before and an after. He does not wait, change, or respond in sequence. He sees all of history at once, in a single changeless "now." This view has deep roots. Boethius defined eternity as "the complete, simultaneous, and perfect possession of boundless life."6 Augustine, Anselm, and Thomas Aquinas all taught something like it. On this picture, God's life has no succession. No tick of the clock. No before or after. And for many theologians, the life of the redeemed shares in this timeless divine life. Heaven is not a place where things happen; it is a state in which everything simply is, all at once.7
The second picture is everlasting duration. On this view, eternity is not the absence of time but the fullness of it. God is eternal in the sense that He has no beginning and no end, but He experiences real sequence. He acts, then responds. He speaks, then listens. He creates, then sustains. And the life of the redeemed, in turn, unfolds in real time. Heaven has a "next." The new creation has mornings. As R. T. Mullins puts it, the divine temporalist holds that God "can undergo a succession of moments," and that eternity means endless duration, not the freezing of all duration.8
The difference between these two pictures is not a small one. On timelessness, change is ruled out by definition. On everlasting duration, change remains possible. And for the case I am building, that difference decides everything.
Let me be precise about what the argument requires. It does not need every detail of the philosophy of time to be settled. It does not need a particular theory of God's metaphysical relationship to time. It needs one thing: real duration after death.
By "real duration" I mean this: that the afterlife includes a genuine sequence of moments in which things can happen. A person can be addressed. A person can reflect. A person can choose. A person can change. None of this requires that the duration be physical or spatial. It does not require bodies, clocks, or orbiting planets. It requires only that there be a real "then" after a given "now."9
The timeless picture cannot supply this. If the final state of the redeemed is a single changeless instant, then no one in it can decide, reflect, or grow. There is no room for appeals. There is no room for a gradual, freely chosen turning toward God. The very idea of "patience" requires time in which to be patient.10
On the timeless picture, everyone who arrives in eternity arrives finished. Whatever they are at the threshold, they are forever. There is no threshold to cross gradually, because there is no "gradually." And if there is no room for change after death, then the offer of postmortem grace has no place to land. A soul that arrives rebellious stays rebellious. Not because God gives up, but because the metaphysics forbid any further movement.
The everlasting picture, by contrast, gives us everything we need. If eternity is real duration, then God can encounter each person across an endless sequence of moments. He can fit each appeal to where that person stands right now. He can wait. He can invite again. He can meet them where the last invitation left off. The long healing (Chapter 20) can proceed step by step. The optimal grace of Chapter 15 can unfold across as many encounters as love requires.11
I am not claiming that eternal duration guarantees universal salvation. Freedom is real, and I said so in Chapter 17. But duration makes the case possible. It provides the stage. Without it, the play cannot even begin.
So which picture should we prefer? I believe there are strong reasons, both philosophical and theological, to think that eternity includes real duration. Let me name four of them.
First, divine action in Scripture is sequential. When the Bible describes God, it describes a God who acts in time. He creates, then rests. He calls Abraham, then waits for his response. He sends prophets, then sends His Son. He raises Jesus from the dead, and that event has a before (the cross, the tomb) and an after (the appearances, the ascension). The entire narrative of Scripture is a narrative, and narratives require sequence.12 A timeless God who does not experience sequence must somehow be the author of all this sequential action without Himself being in any sequence. That is, at minimum, a puzzle. Many philosophers of religion have concluded it is more than a puzzle; it is incoherent.13
Second, the Incarnation puts God inside time. If the eternal Son of God took on human nature, lived a human life, experienced hunger and fatigue and grief and death, then God has been in time. He has experienced a before and an after. This does not settle every question about God's eternal nature, but it creates a strong presumption. A God who enters time at least can be in time. And if He can be in time, then the idea of timelessness as a strict requirement for deity is weakened considerably.14
Mullins on Divine Temporality
R. T. Mullins argues that the standard Christian story, taken at face value, fits naturally with divine temporality. God's desire is to enter "into everlasting friendship with human persons," and the afterlife "comes in two stages," the intermediate state and the general resurrection, in which persons are "given new bodies, judged by God, and given everlasting life." This two-stage structure is itself temporal: one stage follows another. A timeless instant cannot have stages.
Paraphrased from R. T. Mullins, From Divine Timemaker to Divine Watchmaker, ch. 8
Third, the saved are persons, and persons persist through change. Mullins argues at length that presentism and endurantism (the view that a person endures as one and the same entity through time) give us the best account of personal survival after death. On his account, the combination of substance dualism, endurantism, and presentism "has the best fit with the Standard Christian Story."15 The numerically same person who lives, dies, and is raised must persist across real moments. If the afterlife is timeless, there are no moments to persist across. The person who mourned in this life and the person who is comforted in the next must be one and the same, and sameness across time requires time.16
Fourth, rival views of time create serious problems for salvation and afterlife. Mullins devotes several chapters to showing that non-presentist ontologies of time (eternalism, the growing block, hypertime, eschatological presentism, the moving spotlight) each create what he calls "The Problem of No Salvation" and "The Problem of No Afterlife." On eternalism, for example, all moments of the timeline are equally real and fixed, so that evil is never really defeated and the person who suffers is not the same person who is comforted (they are different temporal parts of a spacetime worm). On eschatological presentism, the moment of resurrection is co-present with the Big Bang, and it is hard to see how anything in between could causally contribute to what happens at the resurrection.17
Think about what this means for the basic Christian hope. Jesus promises that those who mourn will be comforted. That promise requires that the person who mourned and the person who is comforted be one and the same. It requires that mourning come first and comfort come after. It requires a real before and a real after. Presentism, combined with endurance through time, gives us exactly this. The same Morag who suffered on earth is the same Morag who will be healed in the resurrection. Not a copy. Not a different temporal stage. The same person. And that sameness across real time is what makes healing, growth, and restoration possible.
Scripture does not speak of eternity as a timeless void. It speaks of it as rich, unfolding life.
Consider the word that does so much work in the New Testament: the Greek word for "age" (aiōn, and its plural, aiōnes). The New Testament does not say believers are taken out of time into a changeless state. It says they enter "the ages to come." Paul writes to the Ephesians that God raised us up with Christ "so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus" (Ephesians 2:7).18
"So that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus." (Ephesians 2:7, ESV)
Notice the plural: ages, not a single frozen moment. And notice the purpose: "that he might show." Showing is an action that unfolds. It is something God does to us across time. The riches of grace are not displayed all at once in a single flash; they are revealed across ages, gradually, in an ongoing act of kindness. This is the language of duration, not of timelessness.19
Peter offers another clue. "With the Lord one day is as a thousand years, and a thousand years as one day" (2 Peter 3:8). This is often taken as a statement about God's transcendence of time, and so it is. But notice what it does not say. It does not say God has no days. It says His experience of time is different from ours. A thousand years is not nothing to God; it is like a day. A day is not nothing; it is like a thousand years. Time is real for God; it simply does not constrain Him the way it constrains us.20
And then there is the tree of life. In Revelation 22:2, John sees the tree "yielding its fruit each month, and the leaves of the tree were for the healing of the nations."
"On either side of the river, the tree of life with its twelve kinds of fruit, yielding its fruit each month. The leaves of the tree were for the healing of the nations." (Revelation 22:2, ESV)
Each month. The tree bears fruit on a schedule. The leaves are for healing, and healing is a process. The new creation, as John sees it, is not a timeless photograph. It is a garden that grows. And nations are being healed in it. If John's vision means anything at all, it means that the life to come has seasons, cycles, growth, and ongoing restoration.21
Eternity as Rich Time, Not No Time
The biblical picture of the life to come is not a frozen "now." It is a world with mornings and months, with fruit trees and rivers, with ongoing acts of divine kindness across "the ages to come." Eternity in Scripture is not the absence of time. It is time made full, freed from decay and death but not from sequence. This is exactly what the universalist argument needs: not a timeless void, but a living duration in which God's patience has room to work.
Now I can state the constructive claim that closes Part Five.
If eternity is real, unbounded duration, then God's patience has a stage without limit. There is no deadline on grace except death, and we have already argued that death is not that deadline (Chapter 19). There is no point at which the offer expires. There is no moment after which God says, "I am done asking." God never runs out of time, because time does not run out.22
This does not mean that salvation is guaranteed by the mere passage of time. I want to be clear about that. Time alone does not save anyone. If a person could refuse God in their first encounter, they could refuse Him in their ten-thousandth. Freedom is real. The bare logical possibility that someone might hold out forever cannot be eliminated by adding more moments (Chapter 17).23
But here is what unbounded time does. It gives God room. It gives optimal grace (Chapter 15) an endless sequence of perfectly fitted occasions. It gives the long healing (Chapter 20) a road without a wall at the end. It means that a person does not have to be healed fast. They only have to be healed surely. And "surely" is exactly the kind of claim this book makes: not that universal salvation is a logical certainty, but that a God of infinite patience, infinite wisdom, and infinite love, working across an eternity of real moments, will in practice win every heart.24
Think of it this way. If you had forever to learn a language, and the best possible teacher was always available, and the teacher knew exactly which lesson you needed next, and the teacher loved you and would never give up, would you eventually learn? You are not forced. You could refuse each lesson. But given an infinite number of perfectly fitted invitations, the probability of permanent refusal shrinks without limit. It does not reach zero (freedom prevents that), but it gets so close to zero that the outcome is, for all practical purposes, certain.25
That is the claim. Not that time does the saving. God does the saving. But time gives God room to save gently. And eternity gives Him all the room there is.
The Constructive Claim
With real, unbounded duration after death, every element of the case comes together. God can encounter each person across an endless series of moments. He can fit each appeal to where that person stands. He can wait without limit. The long healing can unfold at whatever pace freedom allows. No one has to be healed fast; they only have to be healed surely. Time does not save. God saves. But eternity gives Him all the time He needs.
Part Five is now complete. In three chapters we have cleared three obstacles. Death does not end the offer (Chapter 19). Personal identity survives the long transformation (Chapter 20). And eternity provides the real, unbounded duration in which the healing happens (this chapter). The stage is set. Every element of the positive case is now in place.
The question of God's relationship to time has drawn some of the best minds in the philosophy of religion. Let me set the lines plainly.
R. T. Mullins has built the most thorough recent case for divine temporality. His earlier work, The End of the Timeless God, argued that the Christian God cannot be coherently described as timeless.26 His more recent From Divine Timemaker to Divine Watchmaker extends the case across five questions: what time is, how God is responsible for its existence, what it means to call God temporal, what structures time might have, and what the implications are for doctrines including the Trinity, creation, providence, and life after death.27 For this chapter, the most important contribution is his demonstration that presentism and endurantism give the best metaphysical fit with the standard Christian story of salvation and resurrection, and his careful arguments that rival temporal ontologies (eternalism, fragmentalism, hypertime, eschatological presentism, the moving spotlight) each generate deep problems for the afterlife and for the defeat of evil.28
I should be clear: Mullins is not a universalist. He does not argue for the final salvation of all. His work is about the philosophy of time, not soteriology. But his conclusions about divine temporality and the structure of the afterlife provide the metaphysical scaffolding that the universalist case needs. If he is right that eternity must include real duration for persons to persist, be healed, and enjoy fellowship with God, then the universalist can build on that foundation. The soteriology, the claim that God will actually win every heart, comes from the rest of this book.29
On the other side, Brian Leftow and Paul Helm have defended divine timelessness with rigor and care. Leftow argues that God exists in a timeless present that is not a moment of time but a different kind of existence altogether. Helm holds that God's eternal decree fixes the entire timeline at once, so that time is something God creates and governs rather than inhabits.30 Both thinkers are serious, and their views have a long pedigree. I do not dismiss them. But I note that neither account gives us what the universalist argument needs: real, ongoing duration in the afterlife during which persons can freely change. If their view is correct, then the case for gradual postmortem healing must either find another route or accept a significant limitation.
William Lane Craig represents a middle path. He affirms divine temporality (God entered time at creation and has been temporal ever since) while also affirming Molinism, the view that God knows what every free creature would do in every possible situation. Craig's combination of temporal duration and middle knowledge gives us much of the framework this book relies on: a God who is in time, who knows what each person would freely choose, and who can arrange encounters across an endless series of real moments.31 Craig is not a universalist. But his metaphysics, combined with the theology of love and grace this book has built, point strongly in that direction.
Mullins himself engages Craig's position in some detail. He notes that Craig, as a Molinist, affirms a presentist view of time alongside divine temporality. On this combination, the future is settled in God's knowledge (He knows what will happen) but causally open (creatures still make real choices that contribute to the outcome). This is exactly the metaphysical picture this book uses. God knows what each person would freely do. He acts across real time. And His knowledge, combined with His patience and love, allows Him to bring every encounter to bear on the person's eventual free response.
Objection: "You Are Revising the Doctrine of God"
"Classical theism has always said God is timeless and immutable. If you require divine temporality, you are changing the doctrine of God just to save your conclusion. That is theology in reverse: building your picture of God around your soteriology instead of the other way around."
This is a fair objection, and I want to answer it carefully.
First, the debate between divine timelessness and divine temporality is a live one among orthodox Christian philosophers. It is not a dispute between orthodoxy and heresy. Thinkers on both sides affirm the creeds, the Trinity, and the full deity of Christ. Mullins, Craig, Alan Padgett, Nicholas Wolterstorff, and many others have argued for divine temporality while remaining firmly within historic orthodoxy.32 So the charge that divine temporality is a revision of orthodoxy is too strong. It is a revision of one classical model, but not of the faith itself.
Second, and more importantly, my argument does not require full divine temporality. It requires something weaker: that eternity includes real duration for creatures. Even a theologian who holds that God is timelessly eternal can still affirm that the created afterlife has real sequence. God might stand outside time while giving His creatures time to grow, heal, and respond. The question is not whether God is in time, but whether the redeemed are. And almost every Christian theology, including the most classical, affirms that resurrected persons are embodied, active, and living. Embodied life is life in time.33
So the case survives even if divine timelessness turns out to be correct. All it needs is creaturely duration after death. And that is something nearly every Christian tradition already affirms.
Objection: "Endless Time Makes Salvation Trivially Easy"
"If God has forever to work on each person, then everyone gets saved eventually just by the passage of time. Given infinity, anything that can happen will happen. You have made salvation cheap and automatic."
This objection confuses what time does with what God does.
Time alone saves no one. A person could stand in the presence of God for a trillion ages and still say no. Freedom is real, and I have insisted on that throughout this book (Chapter 13). The mathematical claim that "given infinity, anything possible will happen" is simply not true for free choices. A free agent is not a coin flip. It is not the case that, given enough flips, every outcome must occur. A free person can hold a settled disposition indefinitely.34
What endless time does is give God room. Room to keep appealing. Room to keep presenting truth. Room to keep loving. The saving work is done by God, through His grace, His patience, His perfectly fitted appeals, and His own unveiled presence. Time is the medium, not the cause. And the outcome is not "anything happens eventually." The outcome is that the wisest, most loving, most patient Being in existence, who knows exactly what each person would freely choose in every possible situation, has an unbounded number of occasions on which to offer exactly the right invitation. That is not trivial. That is the most serious and personal salvation imaginable.35
The case remains probabilistic, not certain. I have said from the start (Chapter 2) that the conclusion is held as overwhelming conviction, not proof. The one open question is still open. But endless time, combined with infinite wisdom and tireless love, makes the probability of universal success so high that the hope is not merely a wish. It is a reasoned conviction.
Endless Time Is Not a Loophole
A sentimental universalism might say: "Since there is always more time, nothing matters very much. Sin has no urgency. Repentance can wait. Everyone will get there eventually." That is not the claim of this book. This book holds that sin is real, that judgment is real, and that the purifying fire of God's love is severe (Chapter 12). Endless time is not a loophole that lets anyone off. It is the room a patient God uses to heal the unwilling into the willing. That healing still takes their yes. And yes, spoken freely, is never cheap.
Here is what this chapter has argued. The whole positive case for the larger hope rests on a premise about eternity: that life after death includes real duration. I have argued that this premise is well grounded. The philosophical case for divine temporality is strong and growing. The biblical language of "the ages to come," of monthly fruit, and of ongoing acts of divine kindness all point to eternity as rich time, not no time. And even without full divine temporality, nearly every Christian theology grants that creatures in the afterlife experience real, unfolding life.
With this premise in place, the positive case is complete. God is love, and love wills the good of every person (Chapter 4). That love is inescapable in its reach (Chapter 5). Justice is restorative, not merely retributive (Chapter 8). The fire of God's presence purifies rather than destroys (Chapter 12). Freedom is real but not a barrier to grace (Chapter 13). God's knowledge of what each person would freely choose gives Him the ability to save without forcing (Chapter 14, Chapter 15). Death does not end the offer (Chapter 19). The long healing preserves the person who is healed (Chapter 20). And eternity gives God all the time He needs (this chapter).36
What remains now is the hardest part: the objections. The strongest critics have named what they believe is wrong with this hope. I owe them an honest answer. And that is where the book turns next, in Part Six.
But before we leave Part Five, let me say one more thing. The hope I am describing is not the hope that time will wear people down. It is the hope that love will win them over. Time is just the room in which love works. And eternity means that love never runs out of room.
↑ 1. The tension between timelessness and the possibility of postmortem change has been noted by several philosophers. If eternity is a single changeless state, then any model of gradual sanctification or healing after death becomes metaphysically incoherent. See R. T. Mullins, From Divine Timemaker to Divine Watchmaker: An Exploration of God’s Temporality (London: Routledge, 2025), ch. 13, where Mullins argues that eschatological presentism faces precisely this problem.
↑ 2. The assumption of real temporal duration after death runs through the philosophical universalist literature, though it is rarely examined as a standalone premise. Thomas Talbott’s The Inescapable Love of God, 2nd ed. (Eugene, OR: Cascade, 2014) assumes duration when speaking of God’s continued pursuit; Eric Reitan and John Kronen’s God’s Final Victory: A Comparative Philosophical Case for Universalism (New York: Continuum, 2011) assumes it in their cost-comparison argument. This chapter makes the assumption explicit.
↑ 3. The popular Christian imagination of heaven almost universally involves time. Worship unfolds in sequence; relationships grow; knowledge of God deepens. C. S. Lewis captures this intuition in The Last Battle (1956): “Further up and further in!” The image is of a journey, not a destination.
↑ 4. See Chapter 17 for the full argument. The infinite-opportunity structure requires an actual infinity of distinct moments, each carrying a genuine appeal.
↑ 5. See Chapter 15 for the non-coercion argument and the concept of optimal grace. Jerry Walls develops a model of persuasive grace that works through personal encounter, not instantaneous fiat, in Purgatory: The Logic of Total Transformation (Oxford: Oxford University Press, 2012). Such encounters require temporal sequence.
↑ 6. Boethius, The Consolation of Philosophy, Bk. V, Prose 6. The Latin is aeternitas est interminabilis vitae tota simul et perfecta possessio. This definition shaped the classical tradition from Anselm through Aquinas. On its influence, see Brian Leftow, Time and Eternity (Ithaca: Cornell University Press, 1991), 54.
↑ 7. Thomas Aquinas develops the classical timelessness position in Summa Theologiae I, Q. 10. Paul Helm offers the fullest recent defense in Eternal God: A Study of God Without Time, 2nd ed. (Oxford: Oxford University Press, 2010). Mullins identifies the classical commitment to presentism and endurantism within this tradition; see From Divine Timemaker to Divine Watchmaker, ch. 1.
↑ 8. R. T. Mullins, From Divine Timemaker to Divine Watchmaker, preface and Section III (“In Defence of Divine Temporality”). Mullins distinguishes divine temporality (God experiences real succession) from divine timelessness (God exists in a changeless instant). His earlier work, The End of the Timeless God (Oxford: Oxford University Press, 2016), argued that divine timelessness is incoherent.
↑ 9. The minimal requirement is what philosophers of time call “temporal becoming”: a genuine transition from one state to another. This is the core of what A-theorists of time (those who hold that the passage of time is real) affirm. For a survey, see Ulrich Meyer, The Nature of Time (Oxford: Oxford University Press, 2013).
↑ 10. The concept of divine patience (makrothymia, “long-suffering”) presupposes duration. God is described as patient throughout Scripture (e.g., 2 Peter 3:9, Romans 2:4), and patience is not a property a timeless being can have in any straightforward sense. See also Chapter 3 on the character of God.
↑ 11. The connection between optimal grace and temporal duration is tight. If God knows what each person would freely choose in every possible situation (middle knowledge; see Chapter 14) and has an unbounded series of moments in which to act, He can select the most effective appeal for each moment. Time gives middle knowledge its stage.
↑ 12. The narrative structure of Scripture has been recognized as a challenge to divine timelessness by numerous philosophers. Nicholas Wolterstorff argues that a God who acts in history must be in time; see his discussions in Inquiries into Truth and Interpretation and related works. Mullins summarizes the point in From Divine Timemaker to Divine Watchmaker, ch. 7 (“Divine Sovereignty and Providence”).
↑ 13. See Mullins, The End of the Timeless God. Mullins argues that divine simplicity, immutability, and timelessness, taken together, make it impossible to account for God’s real interaction with the world. William Hasker raises similar concerns in his critical engagement with Helm and Rogers; see From Divine Timemaker to Divine Watchmaker, ch. 2, for Mullins’s discussion of these models.
↑ 14. The Incarnation is a particularly strong challenge to strict divine timelessness. If the Son of God assumed a human nature that existed in time, then at least one divine person has a temporal mode of existence. This does not by itself prove that God’s essential nature is temporal, but it does weaken the claim that temporality is incompatible with deity. See Mullins, From Divine Timemaker to Divine Watchmaker, ch. 6 (“The Trinity”), for a discussion of temporality and the Trinitarian persons.
↑ 15. R. T. Mullins, From Divine Timemaker to Divine Watchmaker, ch. 10 (“Contra Eternalism”). Mullins argues that substance dualism, endurantism, and presentism together provide the prior conditions needed for God to bring about the fulfillment of Jesus’s promises in Matthew 5: that those who mourn will be comforted, those who thirst for righteousness will be satisfied, and those who are persecuted will be rewarded.
↑ 16. See Chapter 20 for the full argument on personal identity and moral transformation across time. Mullins’s discussion of the “Problem of Temporary Intrinsics” in ch. 8 of From Divine Timemaker to Divine Watchmaker shows why endurantism combined with presentism avoids the identity problems that plague four-dimensionalist views.
↑ 17. On eternalism and the afterlife, see Mullins, From Divine Timemaker to Divine Watchmaker, ch. 10. On eschatological presentism, see ch. 13, where Mullins argues that the co-presence of the resurrection moment with earlier moments of time makes it impossible for earlier events to causally contribute to the resurrection, and that personal identity is not preserved across the gap.
↑ 18. The Greek is en tois aiōsin tois eperchomenois, “in the ages that are coming upon [us].” The plural aiōnes (“ages”) is significant: Paul envisions not a single moment of glory but a succession of ages in which God’s grace is progressively revealed.
↑ 19. For the significance of the aiōn/aiōnios word group in the New Testament, see Ilaria Ramelli and David Konstan, Terms for Eternity: Aiônios and Aïdios in Classical and Christian Texts (Piscataway, NJ: Gorgias Press, 2007). The term carries the sense of “pertaining to an age” or “age-long,” which is inherently temporal.
↑ 20. The context of 2 Peter 3:8 is significant. Peter is answering those who scoff at the promise of Christ’s return on the grounds that too much time has passed. His answer is not that God is outside time but that God measures time differently. The delay is not indifference but patience (makrothymia). See 2 Peter 3:9: “The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance” (ESV).
↑ 21. Revelation 22:2 has often been read symbolically, and the monthly fruit may carry symbolic freight (twelve kinds for twelve months, perhaps echoing Ezekiel 47:12). But even as symbol, the image presupposes temporal sequence. A symbol drawn from time-bound processes (growing, fruiting, healing) loses its meaning if the reality it symbolizes is utterly timeless.
↑ 22. See Chapter 19 for the argument that death is not a metaphysically privileged deadline on grace. If death is not the deadline and eternity is real duration, then God’s offer has no expiration.
↑ 23. See Chapter 17 for the full treatment of the one open question: whether anyone could refuse God forever. This chapter does not replace that argument but supplies the temporal premise it needs.
↑ 24. The cumulative case is assembled in Chapter 29. The conviction is probabilistic, not deductive (see Chapter 2). Here the temporal premise adds one more element: the case is strengthened, not completed, by the recognition that eternity gives God unlimited occasions for the appeal of grace.
↑ 25. The analogy is imperfect. Learning a language is not a free choice in the same sense as responding to God in faith. But the structural point holds: infinite well-fitted opportunities, offered by a perfect agent, in an unbounded series, generate a probability of success that approaches 1 without reaching it. The gap between “approaches 1” and “equals 1” is where the one open question lives.
↑ 26. R. T. Mullins, The End of the Timeless God (Oxford: Oxford University Press, 2016). Mullins argues that the core attributes ascribed to the timeless God (simplicity, immutability, impassibility) are either incoherent or incompatible with central Christian doctrines.
↑ 27. R. T. Mullins, From Divine Timemaker to Divine Watchmaker: An Exploration of God’s Temporality (London: Routledge, 2025). The five questions are stated in the preface and govern the book’s structure.
↑ 28. On eternalism, see Mullins, From Divine Timemaker to Divine Watchmaker, ch. 10 (“Contra Eternalism”). On fragmentalism, ch. 11. On hypertime and the morphing block, ch. 12. On eschatological presentism, ch. 13. On the moving spotlight, ch. 14. Each chapter argues that the rival ontology creates serious problems for personal persistence, salvation, and/or the afterlife.
↑ 29. This is a methodological point worth stressing. Mullins provides the metaphysics of time; this book provides the theology of salvation. The two are compatible but logically independent. A reader who accepts Mullins’s arguments about temporality is not thereby committed to universalism, and a reader who rejects universalism is not thereby committed to rejecting Mullins on time.
↑ 30. Brian Leftow, Time and Eternity (Ithaca: Cornell University Press, 1991); Paul Helm, Eternal God: A Study of God Without Time, 2nd ed. (Oxford: Oxford University Press, 2010). Both defend divine timelessness as a coherent and scripturally warranted position. Mullins engages both extensively in From Divine Timemaker to Divine Watchmaker, chs. 1–2 and Section III.
↑ 31. On Craig’s combination of divine temporality with Molinism and presentism, see William Lane Craig, The Only Wise God: The Compatibility of Divine Foreknowledge and Human Freedom (Grand Rapids: Baker, 1987); and J. P. Moreland and William Lane Craig, Philosophical Foundations for a Christian Worldview (Downers Grove: InterVarsity Press, 2017), 526–527. Mullins discusses Craig’s position in From Divine Timemaker to Divine Watchmaker, ch. 7.
↑ 32. For a survey of the timelessness-versus-temporality debate among orthodox Christian philosophers, see Gregory E. Ganssle, ed., God and Time: Four Views (Downers Grove: InterVarsity Press, 2001). Contributors include Helm (timelessness), Craig (temporal from creation onward), Alan Padgett (relative timelessness), and Nicholas Wolterstorff (unqualified temporality). All affirm classical Christian orthodoxy.
↑ 33. The point that embodied creatures experience temporal sequence is nearly universal across Christian traditions. Even Aquinas, who held that God is timeless, affirmed that the resurrected body will be a real physical body in a real physical environment. If that body eats, walks, and worships, it does so in time. The timelessness in Aquinas belongs to God, not to the eschaton of the saints.
↑ 34. The mathematical principle sometimes invoked here (if an event has a nonzero probability, then over infinite trials it must eventually occur) applies only to independent, identically distributed random events, not to the free choices of a rational agent. A person’s probability of accepting grace in a given encounter is not fixed and is not independent of prior encounters. It can go up (as understanding grows) or hold steady (if resistance is settled). The one open question in Chapter 17 takes this seriously.
↑ 35. See Chapter 15 on optimal grace and the non-coercion argument. The point is that God does not merely add time; He fills the time with perfectly chosen appeals, drawn from His knowledge of what each person would freely choose (see Chapter 14 on middle knowledge).
↑ 36. The full cumulative case is assembled and weighed in Chapter 29. Each element named here receives its own chapter, and each chapter is linked so the reader can return to any argument in full.
