Had to read this for a class at Cincinnati Christian University. It wasn't bad, and was not in anyway offensive or "wrong." I just didn't care - I don't particularly like his writing style, and didn't feel like he was saying anything particularly new. I would imagine there are a great deal of people who really could learn a lot from this message - but I think the way the church I'm a part of operates, that this isn't a huge connection point to how I actually live.
I recommend this book for anyone from a Christian background who struggles with perfectionism. Good solid counsel.
Quote from Zbigniew Stypułkowski about an interrogation during WWII: "I never felt it was necessary to justify myself with excuses. When they showed me I was a coward, I already knew it...When they showed me a reflection of myself with all my inadequacies, I said to them, 'But gentlemen, I am much worse than that. ' For you see, I had learned it was unnecessary for me to justify myself. One had already done that for me..."
