Part of being wise is that we do not forget the doctrine of sin. Sin is radical and deep, and capable of many cultural grotesqueries. We see them all the time, and we read about them all the time. Welcome to the spiritual war. Belief that we will win the war is not a denial of the reality of that war. My optimism is not of the kind that denies the existence of the battle. My optimism is of the kind that maintains that we are winning the battle.
