Nothing 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, can be accomplished alone; therefore we are saved by love.
No virtuous act is quite as virtuous from the standpoint of our friend or foe as it is from our standpoint; therefore we must be saved by the final form of love, which is forgiveness.
