I refered to a quote a few posts ago by C.S. Lewis that is worth the price of a 100 books. It comes from his introduction to Athanasius' work on the incarnation. This is some of the best advice I have ever heard on reading. Feast yourself on this.
Don't pass over this opportunity to read this short introduction and the previous post: The Cross and Criticism. After you read, let me know what you think.
