In this book, Georges Stéveny examines what Scripture teaches us about the work of Jesus, who transformed the world through his sacrifice. He analyzes the various explanations of Christ's death put forward throughout the centuries, highlighting both their strengths and weaknesses. From Genesis to Revelation, the author paints a detailed portrait of the biblical images and teachings relating to sin, sacrifice, and redemption. Based on this, he attempts to define the divine nature of Christ, striving to portray him as a God of love rather than a vengeful God.
