Here is a drastic parting of the ways with a theology of glory. The Christ of the Cross takes away the possibility of doing something. The theologian of glory might be able to follow to the point of accepting the truth that Christ has fulfilled all things, but then that will have to be used as a motivational tool to make sure the law gets its due. The point is precisely that the power to do good comes only out of this wild claim that everything has already been done. The language has to break out into preaching. Never mind that when we look to ourselves we find no sign of good works. Never mind our fears and our anxieties. We are looking in the wrong place. Look to Christ! He has done it all. Nothing will be gained by trying to shore up the Old Adam. Christ leaves nothing for the Old Adam and Eve to do. The old can only be killed by the law, not given artificial respiration by recourse to it… To the theologian of the cross the language of grace and faith must be pushed absolutely to this length – until it kills the old and raises the new.
