I had the pleasure of meeting Donald Miller, author of "Blue Like Jazz", who is by far different from your typical evangelical writers. He is no more a conservative, theologically and politically speaking, than a liberal. He is honest and provocative about his life experiences as a follower of Christ.

I really enjoyed the brief time I spent with him. He has a wonderful way of reaching people who hold a negative view of Christians. I recommend his books, "Blue Like Jazz", and "Searching for God Knows What".
