Although the book feels rushed and like an advertisement for other books/courses by the end, the overall impact is so profound that I have to give it five stars. If you are a Christian, you need to read this book. If you are in church leadership, you really MUST read this book. It isn't too long and it is easy to read. The first few chapters are absolutely transformative and the last few chapters only suffer because they try to pack in too much information (and thus require referencing other resources). This book has changed how I do things within my family and how I interact with my church family.
