I definitely agree about the East Germany chapters. I read the book a while ago, so I don't remember many of the details, only that I enjoyed it. It sounded like (if I remember correctly) most of his family, growing up, was less active, and some might have been nonmembers; fortunately, they also sounded like good, genuine people, much to his (and our) benefit.
My favorite thing about him is that he has his head on straight. In other words, he knows what the most important things are in life, and we could definitely use an example from someone like that. How many of the worlds problems could be solved if more people had the same priorities!
