Narrator: "When Christ calls a man," Dietrich Bonhoeffer writes, "he bids him come and die." This stark, unsettling statement forms the core of a theological masterpiece written in the shadow of the Nazi regime. It poses a profound question: What does it truly mean to follow Jesus? In a world where faith can become a comfortable doctrine or a set of intellectual principles, Bonhoeffer saw a dangerous perversion of the gospel. He witnessed a Christianity that had become easy, convenient, and ultimately, powerless. His response was The Cost of Discipleship, a powerful and urgent call to rediscover the radical, life-altering, and often painful path of true faith. The book argues that the modern church has fallen prey to a deadly enemy, an enemy that looks like a friend but is, in fact, a poison that kills the very life of discipleship.

Narrator: Bonhoeffer begins by identifying the central problem plaguing the Church: the preaching of "cheap grace." He defines this as grace without a price, forgiveness without repentance, and communion without confession. It is a system that justifies sin but fails to justify the sinner. Cheap grace allows a person to claim the benefits of salvation while remaining utterly unchanged, living a life indistinguishable from the world. It’s a grace sold as a commodity, a doctrine that offers comfort without demanding transformation.

To illustrate the perversion of this idea, Bonhoeffer turns to the story of Martin Luther. Luther’s journey as a monk was a desperate, all-consuming quest for a gracious God. He subjected himself to extreme discipline, trying to earn God’s favor through works. His breakthrough came when he rediscovered the gospel of costly grace—the stunning realization that God’s forgiveness is a free and unconditional gift. However, Bonhoeffer argues that Luther's followers tragically twisted this profound truth. They took the doctrine of justification by faith and severed it from the call to discipleship. Grace became an intellectual principle, a blank check that covered all future sins, rather than the life-altering call to follow Christ that it was for Luther. This, Bonhoeffer warns, is the poison that has killed the life of following Christ, turning the Church into a purveyor of cheap grace and robbing the gospel of its power.

Narrator: In direct opposition to cheap grace stands "costly grace." This is the treasure hidden in the field, for which a person will gladly sell all they have. It is the pearl of great price that demands everything. Costly grace is the gospel that must be sought again and again, the gift that must be asked for. It is costly because it calls us to follow Jesus Christ, and it is grace because in following, we are given the only true life. This grace justifies the sinner, not the sin. It is inseparable from discipleship.

The story of the rich young ruler powerfully illustrates this concept. A young man approaches Jesus, asking what he must do to inherit eternal life. He has followed all the commandments since his youth and believes he is on the right path. But Jesus presents him with the call of costly grace: "If thou wilt be perfect, go and sell that thou hast, and give to the poor... and come and follow me." The young man goes away sorrowful, because he is unwilling to pay the price. He is attached to his possessions, his security, and his old life. He wants the assurance of salvation, but he is not willing to enter into the radical, insecure, and all-consuming life of discipleship. His story reveals that true faith is not about adhering to a set of rules, but about a complete and total surrender to the person of Jesus Christ, breaking with anything that stands in the way.

Narrator: The call to follow Jesus is an individual one, but it does not lead to isolation. Instead, it creates a new, visible community—the Church. Jesus tells his followers, "Ye are the salt of the earth... Ye are the light of the world. A city set on a hill cannot be hid." This means discipleship is not a private, hidden affair. It is a public witness, an "extraordinary" life that is visibly different from the world. This community is defined by its "better righteousness," a life of love, meekness, and peace that shines before others.

Bonhoeffer’s own life provides a stark example of this principle. In 1939, friends in America arranged for him to leave Germany, offering him safety from the inevitable war and Nazi persecution. He was secure. Yet, after a short time, he made the agonizing decision to return. He wrote to his friend Reinhold Niebuhr, "I shall have no right to participate in the reconstruction of Christian life in Germany after the war if I do not share the trials of this time with my people." He chose to return to the visible community of suffering believers in Germany, knowing it would likely cost him his life. He understood that discipleship required him to be a visible witness, to share in the cross of his brothers, and to live out his faith not in the safety of exile, but in the heart of the conflict.

Narrator: The visible life of the disciple community is characterized by what Jesus calls a "better righteousness," one that exceeds that of the scribes and Pharisees. This is not a more perfect adherence to the law, but a righteousness rooted in a personal relationship with Jesus. Its most radical and "extraordinary" expression is the command to love one's enemies. This, Bonhoeffer argues, is the defining feature of Christian love, distinguishing it from all other forms of affection.

Jesus illustrates this in the Parable of the Good Samaritan. A lawyer, seeking to justify himself, asks, "Who is my neighbour?" He wants to define and limit the command to love. Jesus responds with a story where the religious and devout pass by a wounded man, but a Samaritan—a despised enemy—stops to show mercy. The Samaritan doesn't ask if the man is worthy; he simply acts with compassion. This is the better righteousness. It is not about interpreting the law, but about doing it. It is about overcoming evil with good, requiting hostility with love, and seeing every person in need as a brother. This love for the enemy, Bonhoeffer explains, takes the disciple along the way of the cross and into fellowship with the Crucified.

Narrator: The ultimate promise and purpose of this costly journey is that followers of Christ are destined to be conformed to His image. This is not a process of self-improvement or imitation. It is a profound, divine transformation. Bonhoeffer explains that humanity was originally created in God's image, but this was lost in the Fall of Adam. Man, in his pride, tried to become like God on his own terms and ended up with a distorted, satanic image of himself.

The only remedy was for God to become like man. In the Incarnation, Jesus Christ took on the form of fallen humanity to restore the lost image. He lived, suffered, and died, bearing the sin of the world. For a Christian to be conformed to the image of Christ, they must therefore be conformed to this incarnate, crucified, and risen Lord. This means a life of crucifixion—a daily dying to sin, self, and the world. It is through this fellowship of suffering, through bearing the cross, that the divine image is recreated in the believer. The goal is not to become a better version of oneself, but to be transformed entirely, reflecting the very image of the Son of God.

Narrator: At its heart, The Cost of Discipleship is a powerful refutation of a comfortable, disengaged Christianity. Bonhoeffer’s central message is that grace and discipleship are inseparable. True grace is not a license for complacency but a radical call to action—a call to follow Jesus, even when the path leads to suffering and death. This is the "costly grace" that transforms the believer and makes the Church a visible light in the world.

Bonhoeffer’s work is more than theology; it is a testament sealed by his own life. He was executed in 1945 for his role in the resistance against Hitler, living out the very principles he so passionately articulated. His final, challenging question to the modern reader is not simply "Do you believe?" but "Are you following?" It is a question that demands we examine the cost of our own faith and consider what it truly means to answer the call to "come and die."
