Our sin is our resistance to going along with God's initiative in making suffering reparative. We are deeply drawn towards God, but we also sense how following him will dislocate and transform beyond recognition the forms which have made life tolerable for us. We often react with fear, dismay, hostility. We are at war with ourselves, and responding differently to this inner conflict, we end up at war with each other. So it is undoubtedly true that the result of sin is much suffering. But this is by no means distributed according to desert. Many who are relatively innocent are swept up in this suffering, and some of the worse offenders get off lightly. The proper response to all this is not retrospective book-keeping, but making ourselves capable of responding to God's initiative. But now if that's what sin is, then one can sympathize with a lot of the modern critique of a religion which focuses on the evil tendencies of human nature, and the need for renunciation and sacrifice. This is not because humans are in fact angelic, or there is no point to sacrifice. It's just that focusing on how bad human beings can be, even if it's to refute the often over-rosy views of secular humanists with their reliance on human malleability and therapy, can only strengthen misanthropy, which certainly won’t bring you closer to God; and propounding sacrifice and renunciation for themselves takes you away from the main points, which is following God's initiative. That this can involve sacrifice, we well know from the charter act in this initiative, but renunciation is not is point.
As sinners we are like addicts - addicted to ourselves and our own projects. The theology of glory simply seeks to give those projects eternal legitimacy. The remedy for the theology of glory, therefore, cannot be encouragement and positive thinking, but rather the end of the addictive desire. Luther says it directly: "The remedy for curing desire does not lie in satisfying it, but in extinguishing it." So we are back to the cross, the radical intervention, end of the life of the old and the beginning of the new. Since the theology of glory is like addiction and not abstract doctrine, it is a temptation over which we have no control in and of ourselves, and from which we must be saved. As with the addict, mere exhortation and optimistic encouragement will do no good. It may be intended to build up character and self-esteem, but when the addict realizes the impossibility of quitting, self-esteem degenerates all the more. The alcoholic will only take to drinking in secret, trying to put on the facade of sobriety. As theologians of glory we do much the same. We put on a facade of religious propriety and piety and try to hide or explain away or coddle our sins.... As with the addict there has to be an intervention, an act from without. In treatment of alcoholics some would speak of the necessity of 'bottoming out,' reaching the absolute bottom where one can no longer escape the need for help. Then it is finally evident that the desire can never be satisfied, but must be extinguished. In matters of faith, the preaching of the cross is analogous to that intervention. It is an act of God, entirely from without. It does not come to feed the religious desires of the Old Adam and Eve but to extinguish them. They are crucified with Christ to be made new.
