Theology is the application of the Word by persons to the world and to all areas of human life. We need theology not because there is something wrong with the Bible, an improper form perhaps, but because there is something wrong with us. The Bible is fine, just as it is. The problem is that we are slow to grasp it, both because of our weakness and because of our sin. So the theologian, like a good preacher, takes the biblical text and explains it to us.
