What is the theme in No Future Without Forgiveness by Desmond Tutu?

The goodness in humanity is a theme in the book. Tutu's Christian theology teaches him that the universe is fundamentally moral in character. The universe is good and it naturally tends towards good despite the fact that the Earth is corrupted by sin. The life, death, and resurrection of Jesus Christ show Tutu that God Himself places incredible value on human life. Human beings therefore have incredible worth that requires others to treat them as equals and as subjects of love, mercy, and grace.
