First things first, this is NOT a Christian book. This book started out so well but devolved into a distortion of Biblical truth and a teacher of false theology. The view of God presented here may be the wishful thinking of the broad populace, but it is not the God present in the Bible as it claims to be. I was disappointed with this because the book had come highly recommended and was written by a missionary's son, but I couldn't finish it. The revisionism was just too offensive.
The story of the father dealing with guilt and loss is powerful, but it feels manipulative in the face of the false theology it starts selling. The one good thing is that the book does show that a personal relationship with God is possible, which many people don't understand. But we cannot form God in our image. We have to allow God to reveal himself to us.
