"We live by revelation, as Christians, as artists, which means we must be careful never to get set into rigid molds. The minute we begin to think we know all the answers, we forget the questions, and we become smug like the Pharisee who listed all his considerable virtues, and thanked God that he was not like other men. Unamuno might be describing the artist as well as the Christian as he writes, "Those who believe they believe in God, but without passion in the heart, without anguish of mind, without uncertainty, without doubt, and even at times without despair, believe only in the idea of God, and not in God himself."
