Our church is planning a study written by Rick Warren - "40 Days of Purpose Driven Life". Has anyone actually read or studied this curriculum and can give me some objective comments? I have not read any of Rick Warren's books, so I do not have any opinion one way or the other. I would appreciate comments if you have actually READ the book and not an opinion based on what you have heard from your friends. This is not to be confused with Warren's book "Purpose Driven Church".
