The prominent Old Testament scholar Otto Kaiser provides foundational knowledge about the person and work of Jesus of Nazareth based on the testimony of the four Gospels in this book. He clarifies the concepts of sin and reconciliation. His aim is to address the alarmingly widespread ignorance and misunderstanding of the central tenets of the Christian faith, namely that Jesus of Nazareth gave his life as atonement for sin and was raised from the dead on the third day.
