I was looking for a short book about the atonement to put on a book rack. Piper’s book will fit that need. However, it is not perfect. As one reviewer said, there is a lot of overlap between the chapters. He is repetitive. Second and more glaring, though typical for Piper, he does not really bring the Old Testament into it. There is no big picture of Jesus as fulfilling the covenant or Jesus as Israel. This might be because he was trying to get at what the atonement achieved instead of what caused it. But at the least one of the reasons Christ came to die was to fulfill Scripture. This is not mentioned explicitly. His failure to incorporate OT themes and the covenant makes this book weaker. He could have taken ten of his reasons out added more OT themes and made the book a lot more robust. Still as a basic lay introduction to Christ’s work it is good.
