We have Gideon because we don't want always to be speaking of our faith in abstract, otherworldly, irrreal, or general terms, to which people may be glad to listen but don't really take note of; because it is good once in a while actually to see faith in action, not just hear what it should be like, but see how it just happens in the midst of someone's life, in the story of a human being. Only here does faith become, for everyone, not just a children's game, but rather something highly dangerous, even terrifying. Here a person is being treated without considerations or conditions or allowances; he has to bow to what is being asked, or he will be broken. This is why the image of a person of faith is so often that of someone who is not beautiful in human terms, not a harmonious picture, but rather that of someone who has been torn to shreds. The picture of someone who has learned to have faith has the peculiar quality of always pointing away from the person's own self, toward the One in whose power, in whose captivity and bondage he or she is. So we have Gideon, because his story is a story of God glorified, of the human being humbled.
