Reinhold Niebuhr.

Nothing worth doing is completed in our lifetime,Therefore, we are saved by hope.

Nothing true or beautiful or good makes complete sense in any immediate context of history;Therefore, we are saved by faith.

Nothing we do, however virtuous, can be accomplished alone.Therefore, we are saved by love.

No virtuous act is quite a virtuous from the standpoint of our friend or foe as from our own;Therefore, we are saved by the final form of love which is forgiveness.
