I really enjoyed reading this book. It took me more than 30 days, but that is okay. It's not intended to be read and set aside, though (or placed in the "read" folder); it is supposed to be read and applied, or at least tested out. I may use it to lead a group one day. It is very easy to read, but Gary challenges the reader to look inward and ask tough questions. I would recommend it to anyone who doesn't know what to do, or finds disappointment, in their Christian life.
