understanding faith.

"The answer is not just a word but the Word; not an idea but a person. Clues are abstract, persons are concrete. Clues are signs; they signify something beyond themselves, something real. Our solution cannot be a mere idea, however true, profound, or useful, because that would be only another sign, another finger, another clue—like fingers pointing to other fingers, like having faith in faith, or hope in hope, or being in love with love. A hall of mirrors."
