About This Study Guide
Dietrich Bonhoeffer wrote The Cost of Discipleship in 1937 — from the context of a Germany sliding into totalitarianism and a church being seduced by compromise — and its central argument has lost none of its urgency. The book's thesis is announced in its very first line: "Cheap grace is the deadly enemy of our Church." Against the comfortable Christianity that demands nothing, Bonhoeffer sets the call of Jesus Christ, which demands everything. True discipleship, he argues, is not a religious program layered on top of ordinary life; it is a new kind of existence, born in obedience to a living Person. The book moves in two major movements: a theological examination of grace and call (Part One), followed by a sustained, verse-by-verse meditation on the Sermon on the Mount and the missionary discourse of Matthew 10 (Part Two). Together, they form one of the most searching challenges to comfortable Christianity ever written.
This study guide is designed for use over thirteen weeks — either in a small group or in personal devotional study. The pattern for each week is simple: read the assigned chapter or section before you meet, spend some time journaling your honest reactions, and then work through the discussion questions together (or alone, in writing). There are no right answers to memorize; the goal is to let Bonhoeffer's relentless questions reach into your actual life. Some weeks will be uncomfortable — that is the point. Bonhoeffer is not trying to give you information about discipleship; he is trying to summon you into it.
By the end of this guide, you will have been confronted — perhaps for the first time — with the full weight of what Jesus asks of those who follow him. You will likely find that some of your assumptions about grace, obedience, the church, and the Christian life need to be rethought. More importantly, you will have spent thirteen weeks in close company with one of the most faithful witnesses of the twentieth century, a man who ultimately paid for his convictions with his life. His words carry the authority of someone who meant every one of them.

Week 1: Introduction — Costly Grace vs. Cheap Grace
Free sampleRead the Preface and Chapter 1 of The Cost of Discipleship ("Costly Grace"). Key passages: Matthew 13:44-46; Luke 14:25-33.
1.Bonhoeffer's opening salvo is: "Cheap grace is the deadly enemy of our Church." Before engaging his argument, what does that phrase stir up in you? Does it sound liberating, alarming, or unfair?
2.Bonhoeffer defines cheap grace as "the preaching of forgiveness without requiring repentance, baptism without church discipline, communion without confession, absolution without personal confession." In your own words, what makes grace "cheap" in his framework — and why does he call it deadly rather than merely inadequate?
3.He then defines costly grace: "It is costly because it costs a man his life, and it is grace because it gives a man the only true life." How does this paradox — that the most demanding thing is also the most freeing — sit with you? Can you think of an experience in your own life where something costly turned out to be genuinely freeing?
4.Bonhoeffer argues that the Lutheran Reformation recovered costly grace but that within a generation, Lutheranism began mass-producing cheap grace — treating the doctrine of justification by faith as a license to live unchanged. Do you see a similar dynamic in any Christian traditions or communities you have been part of?
5.He describes the tragic figure of a Christian who, wanting to live fully in the world, grants himself absolution and goes on unchanged — and then says that such a person has cheapened both grace and the cross. What does this reveal about the relationship between how we think about grace and how we actually live?
a.Where, if anywhere, have you functionally treated grace as a license rather than a call?
b.What would it look like, concretely, to repent of cheap grace?
6.Bonhoeffer says that costly grace is "the call of Jesus Christ at which the disciple leaves his nets and follows." How does locating grace in a specific, personal call from Jesus change its character compared to locating grace in a doctrine or theological system?
7.He famously writes, "When Christ calls a man, he bids him come and die." How does this connect to the gospel itself — to the death and resurrection of Jesus? Is Bonhoeffer being morbid, or is he pointing to something at the heart of Christian identity?
8.As you begin this book, what do you most hope to gain — and what are you most afraid of having challenged?
Week 2: The Call to Discipleship
Read Chapter 2 of The Cost of Discipleship ("The Call to Discipleship"). Key passages: Mark 2:14; Matthew 9:9; Matthew 4:18-22.
1.Bonhoeffer draws attention to the sheer immediacy of the disciples' response in the Gospels: they left their nets and their tax booth "at once," without theological deliberation. Why does he think this immediacy is theologically significant, rather than merely dramatic?
Week 3: Single-Minded Obedience
Read Chapter 3 of The Cost of Discipleship ("Single-Minded Obedience"). Key passages: Matthew 5:29-30; Luke 9:57-62.
1.Bonhoeffer describes what he calls "the great divide" between those who hear Jesus' words and do them, and those who hear and do not. He says this divide is not between serious and casual Christians but between disciples and non-disciples. Does that strike you as too sharp a distinction, or does it ring true?
Week 4: Discipleship and the Cross
Read Chapter 4 of The Cost of Discipleship ("Discipleship and the Cross"). Key passages: Matthew 10:38; Mark 8:31-38; Luke 14:27.
1.Bonhoeffer writes that "to endure the cross is not a tragedy; it is the suffering which is the fruit of an exclusive allegiance to Jesus Christ." What distinction is he drawing between the crosses Christians are called to bear and the ordinary suffering that comes to everyone in a fallen world?
Week 5: Discipleship and the Individual / The Beatitudes
Read Chapters 5-6 of The Cost of Discipleship ("Discipleship and the Individual" and "The Beatitudes"). Key passages: Matthew 5:1-12.
1.Bonhoeffer argues that discipleship creates a new kind of individual — one who has been separated from all previous attachments and securities and placed in direct relationship with Christ. He calls this a "mediation" — Christ stands between the disciple and everything else. How does this image reshape how you think about your closest relationships?
Week 6: Salt, Light, and the Righteousness of Christ
Read Chapters 7-9 of The Cost of Discipleship ("The Salt of the Earth," "The Visible Community," and "The Righteousness of Christ"). Key passages: Matthew 5:13-20.
1.Bonhoeffer argues that the community of disciples is called to be the salt of the earth — but that salt which has lost its flavor is good for nothing. He connects the loss of flavor directly to the loss of costly grace. How does a church that has embraced cheap grace lose its saltiness? Can you give a concrete example?
Week 7: The Antitheses — A Deeper Righteousness
Read Chapters 10-14 of The Cost of Discipleship (covering the antitheses: anger, lust, divorce, oaths, revenge, enemies). Key passages: Matthew 5:21-48.
1.Bonhoeffer reads the antitheses not as Jesus tightening the law into an impossible demand but as Jesus revealing the full human depth the law always intended to reach — anger is the heart of murder, lust is the heart of adultery. How does this reframe the purpose of the law? Is Jesus liberating or convicting you as you read this?
Week 8: The Hidden Righteousness — Piety in Secret
Read Chapters 15-18 of The Cost of Discipleship (on almsgiving, prayer, fasting, and treasures). Key passages: Matthew 6:1-21.
1.Bonhoeffer argues that "righteous" acts done to be seen by others — almsgiving, prayer, fasting — are not discipleship but its imitation, and he calls this the "most dangerous" form of religious corruption. Why is religious performance more dangerous than open irreligion?
Week 9: The Disciple and the World — Anxiety, Judgment, and the Narrow Gate
Read Chapters 19-22 of The Cost of Discipleship (on anxiety, judging others, the disciple and unbelievers, and the conclusion of the Sermon). Key passages: Matthew 6:19–7:29.
1.Bonhoeffer writes that anxiety is the natural result of trying to secure your own life — it is what happens when your eye is not "single" but divided between God and possessions. He says the antidote is not positive thinking but a reorientation of the whole self toward God. How does this connect to what he said earlier about single-minded obedience?
Week 10: The Messengers — The Mission Discourse
Read Chapters 23-26 of The Cost of Discipleship (on the harvest, the apostles, the work and suffering of the messengers). Key passages: Matthew 9:35–10:42.
1.Bonhoeffer opens this section with Jesus' compassion for the crowds "harassed and helpless, like sheep without a shepherd." He insists that this compassion is the motive for mission — not strategy, not church growth, but the suffering of people who have no shepherd. Does compassion or strategy more often drive your involvement in outreach?
Week 11: The Church and the World — The Body of Christ
Read Chapters 27-30 of The Cost of Discipleship (on the community of Jesus, the image of Christ, the visible church, and the saints). Key passages: Romans 12; 1 Corinthians 12; Ephesians 4.
1.Bonhoeffer argues that the church is the body of Christ — not metaphorically or institutionally, but ontologically. Christ takes form in the world through this community. What does it mean for your understanding of church attendance, church membership, and church conflict if this is true?
Week 12: The Image of Christ — Conformation and Cruciformity
Read the concluding chapters of The Cost of Discipleship (on the image of Christ and the conclusion). Key passages: Romans 8:29; 2 Corinthians 3:18; Philippians 3:10-11.
1.Bonhoeffer argues that human beings were created in the image of God and that this image was shattered in the fall. The entire work of salvation — and of discipleship — is its restoration. How does framing discipleship as image-restoration change its emotional register? Does it feel more like recovery or more like achievement?
Week 13: Review & Reflection — The Cost We Have Counted
No new reading this week. Review your notes, journals, and underlinings from the entire book.
1.When you began this book, how would you have defined discipleship? How would you define it now? What is the most significant change in your understanding?
