Read them!!! And then read some more C.S. Lewis. The Screwtape Letters would be a good place to go after Narnia. He is absolutely incredible. His profound spiritual understanding is so amazing in terms of LDS theology. What an inspired man. Ever notice how many time our Church leaders quote him? Just saw Prince Caspian this weekend and lost count of how many times I saw parallels with our theology. His work touches me so much.
