When I was in my early 20s, I read the book Mere Christianity, by C. S. Lewis. As the title indicates, in this work Lewis tried to get to the core of Christianity, and I think he did a pretty good job. He laid a good foundation by outlining the key elements of the Christian faith. To do this, he wrote a small book of 190 pages; however, Jesus distilled all of the Law and the Prophets into only two sentences.
