I read the book years ago. The movie sounds like an interesting one but I definitely would take note of the decision theology, it is so prevalent these days in so many circles. I work at a funeral home and the sermons that are Lutheran are so hugely comforting. I was recording a funeral recently that was not Lutheran, there was a lot of decision theology in it and the poor family had a pastor, who was a really nice guy, but left the gospel out of the funeral sermon. It was very sad to me. I thank God for the 200 proof Gospel of Jesus Christ's death and resurrection for me. That kind of preaching is becoming a rare treasure.
