From 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.
