"A Christian is not a man who never goes wrong, but a man who is enabled to repent and pick himself up and begin over again after wach stumble- because the Christ-life is inside of him." C.S. Lewis, Mere Christianity

C.S. Lewis is one of my favorite authors of all time. He had a whole lot of wisdom and God was and is able to do great things through Lewis's works. I would strongly suggest that you read Mere Christianity. It is definetly one of the most rewarding books to read besides the Bible.
