The Bible is not a collection of timeless principles offering a gentle thought for the day. It is not a resource for our self-improvement. Rather, it is a dramatic story that unfolds from promise to fulfillment, with Christ at the center. its focus is God and his action. God is not a supporting actor in our drama; it is the other way around. God does not exist to make sure that we are happy and fulfilled. Rather, we exist to glorify God and to enjoy him forever. God is not a facilitator of our “life transformation” projects. He is not a life coach. Rather, he is our Creator, Lawgiver, Judge, and Covenant Lord. As we will see, he is also our Redeemer. However, before we can speak of God’s saving work in Christ we have to reverse the focus from a human-centered to a God-centered way of thinking. The gospel witnesses not to an inner light within self, but to the Light that came into the world, shining in the darkness and overpowering it (John 1:4-9).
