The worst thing a book can do for a Christian is to leave him with the impression that he has received from it anything really good; the best it can do is to point the way to the Good he is seeking. The function of a good book is to stand like a signpost directing the reader toward the Truth and the Life…. The work of a good book is to incite the reader to moral action, to turn his eyes toward God and urge him forward. Beyond that it cannot go.
