He does a good job of describing the differences between religion and Jesus and how/why to focus on Jesus. He also gives a good description of what we should consider to be a church. It would certainly be good reading for someone who makes the claim that they are a Christian based on the perspective that he describes in this book.
This book is a great read for anyone at any stage of their walk with Christ. I think that book is even better for a non believer who may struggle with accepting Christ because of how the 21st Century church and the media has painted Christianity out to be. Great book.
