"Nothing that is worth doing can be achieved in our lifetime; therefore, we must be saved by hope. Nothing which is true or beautiful or good makes complete sense in any immediate context of history; therefore, we must be saved by faith. Nothing we do, however virtuous, could be accomplished alone; therefore, we must be saved by love. No virtuous act is quite as virtuous from the standpoint of our friend or foe as it is from our own standpoint; therefore, we must be saved by the final form of love, which is forgiveness."
-- Reinhold Niebuhr, The Irony of American History (Niebuhr wrote what has become the Serenity Prayer for a sermon in the 1930s, "God, give us grace to accept with serenity the things that cannot be changed, courage to change the things that should be changed, and the wisdom to distinguish the one from the other." The prayer was written on cards that were carried by soldiers during World War II before being adopted in a modified form by Alcoholics Anonymous.)
