It is a radical and almost frightening thought to see that God is actually as much at work in our worst moments of sin and defeat as he is in our best moments of shining obedience. Far from leading us further into sin, this concept draws us into deeper dependence on the promises and the power of God. If he who started a good work in us has promised to complete it, then we are safe. If Scripture shows us a God who is absolutely sovereign over the sins of all people, even those of his own children, then we may be comforted.
