I adore this book. There is a very good reason why this is the best-selling book in the Religion and Philosophy room of Powells Books in Portland (the world's largest independent bookstore); it is the most accessible, human, funny, and compelling "religious book" I've ever read (and I've read many). It is much less like a personal spirituality manual than it is a book of quirky essays by someone who happens to be deeply spiritual and learned, through the ups and downs of his life, how his faith was as much a part of his everyday life as breathing and sleeping.
I also love this book because it was written in Portland, and the house where the author lived turns out to be right across the street from my church. (By the big gold Joan of Arc statue, if you're a Portlander.) And he dedicated the book to all the coffeeshops and bars in Portland where he wrote it, which I thought was really cool.
