Book Club Questions for The Reason for God

The Reason for God by Timothy Keller

Use these 48 free questions to start a thoughtful book club or small-group conversation. They are arranged in the same 16-session order as the complete guide, which includes 112 questions in all.

Week 1

Introduction — The Leap of Doubt

Read the Introduction of The Reason for God by Timothy Keller

  1. 1.Keller describes the congregation at Redeemer Presbyterian in Manhattan as filled with both fervent believers and committed skeptics who sat side by side. What does that picture suggest about the kind of conversation he is trying to create in this book — and what kind of conversation are you hoping to have in this study?

  2. 2.Keller argues that a "leap of doubt" is just as much a faith commitment as a "leap of faith" — that to doubt Christianity requires trusting a set of assumptions that are themselves unproven. Do you find that argument initially compelling or annoying? Why?

  3. 3.He notes that the New Atheist books (Dawkins, Hitchens, Harris, Dennett) were dominating bestseller lists when he wrote this book. Do you think the cultural moment has shifted since 2008, or do the same objections still carry the same emotional weight in your circles?

Week 2

Chapter 1 — There Can't Be Just One True Religion

Read Chapter 1 of The Reason for God by Timothy Keller

  1. 1.Keller opens with the common assertion that "all religions are basically the same" or that "no one religion can be right and the rest wrong." What is the emotional appeal of that view? Where have you heard it most often — from friends, culture, social media?

  2. 2.He uses the illustration of the blind men and the elephant — the familiar parable meant to show that each religion only grasps part of the truth. Keller points out that the person telling the parable has to claim they can see the whole elephant. What does this reveal about the hidden claim embedded in religious relativism?

    a.If someone says "all religions are just different paths to the same truth," what kind of knowledge about religion are they claiming to have?

    b.Is that claim more humble or less humble than simply holding one religion to be true? Explain your reasoning.

  3. 3.Keller distinguishes between "strong" religious exclusivism (my religion is true and yours is worthless) and the unavoidable logic that if two religions make contradictory truth claims, they cannot both be correct. Do you think this is a fair distinction? Can you genuinely respect someone's religion while believing it contains serious errors?

Week 3

Chapter 2 — How Could a Good God Allow Suffering?

Read Chapter 2 of The Reason for God by Timothy Keller

  1. 1.Keller describes sitting with people in his congregation who have experienced devastating loss and who ask, "How could a good God allow this?" Before you engage the arguments, sit with that question personally: Have you ever asked it yourself, or has someone close to you asked it? What did it feel like?

  2. 2.He argues that the existence of suffering does not logically disprove the existence of God — because the argument from suffering requires a standard of "what should be," and that standard itself implies a moral order that points back toward God. Walk through that argument in your own words. Does it hold up?

  3. 3.Keller cites C.S. Lewis's famous statement that his argument against God was that the universe seemed "so cruel and so unjust" — but that this sense of injustice itself presupposed a real standard of justice. How does this "moral argument" function as a response to the problem of evil?

    a.Can a purely materialist worldview account for the intuition that suffering is genuinely wrong and not merely unpleasant?

    b.If there is no God, what is the basis for saying the amount of suffering in the world is "too much"?

Week 4

Chapter 3 — Christianity Is a Straightjacket

Read Chapter 3 of The Reason for God by Timothy Keller

  1. 1.Keller quotes the common complaint that Christianity's moral rules restrict personal freedom and individual self-expression. How prevalent is this objection in the culture around you? Where do you most often encounter it?

  2. 2.He introduces the argument that all communities and all relationships require constraints — that freedom is not the absence of all limits but the presence of the right limits. He uses the example of a fish being "free" in water but not on dry land. How does this reframe the concept of freedom?

    a.Can you think of an area of your own life where a constraint (a commitment, a discipline, a boundary) actually produced more flourishing, not less?

    b.How does this apply to Christian ethics specifically?

  3. 3.Keller argues that a "do whatever feels right to you" ethic is not actually freeing — it simply substitutes the authority of cultural fashion and personal desire for the authority of God. Do you find that persuasive? What are the limits of that argument?

Week 5

Chapter 4 — The Church Is Responsible for So Much Injustice

Read Chapter 4 of The Reason for God by Timothy Keller

  1. 1.Keller acknowledges the genuine historical evils done in the name of Christianity without flinching. How did you respond to his willingness to admit the church's failures? Does intellectual honesty about Christian history strengthen or weaken his overall case, in your view?

  2. 2.He makes the argument that the atrocities committed by Christians were done in direct violation of the teachings of Jesus — and that the reformers and abolitionists who eventually corrected those evils were also motivated by Christian faith. How strong is this argument? Does it excuse the church, or simply clarify what is actually being evaluated?

    a.Is it fair to judge a religion by the worst behavior of its followers, or by its core teachings?

    b.By the same standard, how would secular ideologies like Marxism or nationalism fare?

  3. 3.Keller points out that the 20th century's most systematic violence was carried out by explicitly secular regimes — Nazi Germany, Stalinist Russia, Maoist China — and that this does not make secularism evil any more than the Crusades make Christianity evil. Is this a fair parallel? Why or why not?

Week 6

Chapter 5 — How Can a Loving God Send People to Hell?

Read Chapter 5 of The Reason for God by Timothy Keller

  1. 1.What is your instinctive reaction to the traditional Christian doctrine of hell? Where did that reaction come from — upbringing, culture, personal experience, theology?

  2. 2.Keller argues that the modern objection to hell is based on a particular view of love — that a loving God would never allow permanent consequences for human choices. He pushes back by asking whether a love that overrides all human choices is really love or is actually coercion. How do you respond to that argument?

    a.If God ultimately forces everyone into his presence regardless of their desires, what does that say about the nature of love and personhood?

    b.C.S. Lewis famously said that the doors of hell are locked from the inside. What does that image suggest about human freedom and divine justice?

  3. 3.Keller describes hell not primarily as a place of fire and punishment imposed from outside, but as the trajectory of a self that has curved in on itself — the full, unimpeded consequence of choosing self over God. Does this understanding of hell feel more or less troubling to you than the traditional image? Why?

Week 7

Chapter 6 — Science Has Disproved Christianity

Read Chapter 6 of The Reason for God by Timothy Keller

  1. 1.How prevalent is the assumption that "science has disproved God" in your workplace, school, or social circles? What specific scientific findings or arguments are usually cited to support it?

  2. 2.Keller argues that the "conflict thesis" — the idea that science and religion have always been at war — is a myth invented in the 19th century, and that historically, modern science grew largely out of a Christian intellectual framework. Were you aware of this historical argument? How does it reframe the conversation?

    a.What assumptions about the universe (its rationality, its consistency, its being worth investigating) does science require — and where did those assumptions come from historically?

    b.Can you name any historically significant scientists who were also committed Christians?

  3. 3.Keller carefully distinguishes between evolution as a scientific mechanism and evolution as a philosophical worldview ("evolution proves there is no God"). Why is this distinction important, and do you think most people making the argument are aware of it?

Week 8

Chapter 7 — You Can't Take the Bible Literally

Read Chapter 7 of The Reason for God by Timothy Keller

  1. 1.What is your own history with the Bible — have you read it extensively, occasionally, or rarely? What is your default assumption about its reliability going into this chapter?

  2. 2.Keller notes that the charge "you can't take the Bible literally" often reveals a confusion about what "literally" means. He argues that every careful reader already reads the Bible with genre awareness — distinguishing poetry from history from letter from prophecy. How does this reframe the question of biblical interpretation?

    a.What literary genres can you identify in the Bible? How do you read a poem differently from a historical account?

    b.Does acknowledging genre distinctions undermine biblical authority, or does it actually reflect more careful reading?

  3. 3.He addresses the objection that the Bible has been edited and changed so many times it can't be trusted. Keller points to the field of textual criticism and the remarkable consistency of the biblical manuscripts. Before reading this chapter, how much did you know about the textual history of the Bible? Has your view shifted?

Week 9

Interlude — The Clues of God

Read the Interlude of The Reason for God by Timothy Keller

  1. 1.Keller describes the Interlude as a transition from "clearing away objections" to "building a positive case." Why might this two-step structure be more persuasive than simply leading with arguments for God's existence? What is he assuming about his reader's state of mind?

  2. 2.He introduces several "clues of God" — features of human experience that cry out for explanation: the regularity of nature, the existence of objective moral values, the near-universal human experience of beauty and transcendence. Which of these clues do you find most personally arresting? Which do you find least convincing?

  3. 3.Keller borrows from the philosopher Alvin Plantinga the idea that belief in God can be "properly basic" — that it does not need to be proven from more fundamental premises the way we don't need to prove that our senses are reliable. How do you react to that argument? Does it feel like a dodge, or a genuine philosophical point?

Week 10

Chapter 8 — The Clue of Creation

Read Chapter 8 of The Reason for God by Timothy Keller

  1. 1.Keller opens Part Two by arguing that the skeptic also requires faith — faith that the universe has no personal origin. He says that theism and atheism are both metaphysical commitments that go beyond what science can demonstrate. Do you think that is a fair characterization of atheism?

  2. 2.He engages the cosmological argument: the universe began, everything that begins has a cause, therefore the universe has a cause. And that cause must be outside of space, time, and matter. Walk through this argument carefully. Where do you think its strongest and weakest points are?

  3. 3.Keller discusses the "fine-tuning" of the universe — the remarkable fact that the fundamental constants of physics are calibrated to extraordinarily precise values necessary for any life to exist. How does this fit with the naturalist explanation that everything exists by chance? How does it fit with the theist explanation of a purposeful creator?

    a.The multiverse hypothesis is sometimes proposed as an alternative explanation for fine-tuning. What are the strengths and weaknesses of that hypothesis compared to theism?

    b.Does the fine-tuning argument prove God exists, or does it simply make God's existence more plausible? Is there a difference?

Week 11

Chapter 9 — The Knowledge of God

Read Chapter 9 of The Reason for God by Timothy Keller

  1. 1.Keller opens by observing that virtually all people, in all cultures and times, have shared certain core moral intuitions: that gratuitous cruelty is wrong, that justice matters, that human dignity deserves respect. Where do you think these intuitions come from? What is the strongest naturalistic explanation you have encountered?

  2. 2.He uses the example of condemning the Holocaust: if morality is purely relative to culture or personal preference, on what basis can we say that what the Nazis did was genuinely, objectively wrong — and not merely something we happen to dislike? Walk through the implications of moral relativism taken seriously.

    a.If all moral claims are just expressions of cultural preference, can you make a principled case for human rights?

    b.Most people resist moral relativism when it is pressed to its logical conclusions. What does that resistance itself tell us?

  3. 3.Keller acknowledges that the evolutionary account of morality — that our moral intuitions evolved because they aided survival — is interesting as far as it goes. But he argues it does not vindicate those intuitions as actually true. If our sense of justice is just a survival mechanism, does it give us any reason to follow it when doing so is costly? How do you respond to that challenge?

Week 12

Chapter 10 — The Problem of Sin

Read Chapter 10 of The Reason for God by Timothy Keller

  1. 1.How do you typically hear the word "sin" used in culture — in churches, in media, in everyday conversation? What associations does it carry? How does Keller's definition of sin differ from the typical popular understanding?

  2. 2.Keller defines sin not primarily as "breaking rules" but as building your identity on anything other than God — making something a good thing into an ultimate thing, what Augustine called having "disordered loves." How does this definition expand or clarify your understanding of what has gone wrong in human life?

    a.What are the things in your own life that you treat as ultimate — things whose loss would feel catastrophic to your sense of self?

    b.How does this definition help explain why people who are "moral" by conventional standards can still experience profound emptiness and dysfunction?

  3. 3.He argues that making anything other than God the center of your identity — even something genuinely good, like family, career, approval, or justice — will eventually produce the distortion, anxiety, and harm characteristic of sin. Can you think of examples — either from the book or from your own observation — where a good thing became a destructive thing by being made ultimate?

Week 13

Chapter 11 — Religion and the Gospel

Read Chapter 11 of The Reason for God by Timothy Keller

  1. 1.Keller draws a sharp contrast between "religion" (I obey, therefore God accepts me) and "gospel" (God accepts me in Christ, therefore I obey). Before reading this chapter, how would you have described the relationship between behavior and God's acceptance? Has Keller's framing shifted anything for you?

  2. 2.He argues that most people — including many people in church — are operating on a fundamentally religious rather than gospel-shaped logic: trying to establish their worth before God (and others) through performance. Why is this tendency so persistent, even in people who intellectually know the gospel?

    a.What are the emotional signs that you are operating from a performance-based religious logic rather than gospel-based grace?

    b.How does performance-based religion produce both pride (when you succeed) and despair (when you fail)?

  3. 3.Keller uses the term "moralistic therapeutic deism" (coined by sociologist Christian Smith) to describe the default religion of most Americans: God exists, wants you to be good, and mostly wants you to be happy. How does this description fit the implicit religion of people you know? How does authentic Christianity challenge each of its three elements?

Week 14

Chapter 12 — The (True) Story of the Cross

Read Chapter 12 of The Reason for God by Timothy Keller

  1. 1.Many people find the doctrine of the atonement — that Jesus died as a substitute for sinners — morally troubling, even offensive. What is the most common objection you have heard? Before working through Keller's response, try to state the objection as charitably and powerfully as you can.

  2. 2.Keller presents several models of the atonement — the cross as moral example, as Christus Victor (defeating the powers of sin and death), and as substitutionary atonement — arguing that they are not mutually exclusive but that substitution is the heart that gives the others their meaning. Why does Keller insist that substitution is not one theory among equals but the center?

    a.What is lost if we keep the "moral example" meaning of the cross but remove the substitutionary one?

    b.What does it mean to say that on the cross, God himself absorbed the consequences of our sin rather than simply setting them aside?

  3. 3.Keller uses the profound illustration of forgiveness in human relationships to explain the cross: genuine forgiveness always involves the forgiver absorbing a real cost rather than passing it along. When someone truly forgives a wrong, they do not pretend the wrong didn't happen — they refuse to make the wrongdoer pay. How does this illuminate what God did at the cross?

Week 15

Chapter 13 — The Reality of the Resurrection

Read Chapter 13 of The Reason for God by Timothy Keller. Key passage: 1 Corinthians 15:1–20

  1. 1.Keller quotes Paul's statement in 1 Corinthians 15 that "if Christ has not been raised, your faith is futile." Paul stakes everything on the historical resurrection. How does this differ from a religious worldview that says "it doesn't matter whether it literally happened — the spiritual meaning is what counts"?

  2. 2.He works through the main alternative explanations for the empty tomb and the resurrection appearances — the "wrong tomb" theory, the "hallucination" theory, the "legend" theory — and argues that each fails on historical grounds. Which of these alternative explanations have you encountered? Which did you find most initially plausible, and how does Keller respond to it?

    a.The hallucination theory requires that hundreds of people in different settings had the same hallucination. Why is that psychologically and historically implausible?

    b.The legend theory requires that the resurrection accounts developed over centuries. Why is the early dating of the sources (1 Corinthians 15 is within 25 years of the events) a problem for this theory?

  3. 3.Keller notes that the early Christian accounts of the resurrection describe the witnesses as primarily women — a detail that would have undermined the credibility of the story in the first-century world, since women's testimony was not accepted in Roman courts. Why does this "criterion of embarrassment" give historians more reason, not less, to take the accounts seriously?

Week 16

Review & Reflection

Review The Reason for God by Timothy Keller in its entirety. Consider re-reading key passages or your journal notes from previous weeks

  1. 1.When you wrote down your most pressing question or doubt at the end of Week 1, what was it? Return to it now. How has Keller addressed it — or not? Has your thinking changed, deepened, or stiffened? Be specific.

  2. 2.Which single chapter or argument in the book was most personally impactful for you — the one that most changed how you think or feel? What made it so significant?

  3. 3.Keller's two-part structure (dismantling objections, then building a positive case) is a deliberate apologetic strategy. Looking back: do you think it worked? Did the first half clear enough ground for the second half to land? Or did the positive case in Part Two feel like the stronger material?
