Two quotes from Niebuhr

  The first:

"The task of building a world community is man’s final necessity and possibility, but also his final impossibility. It is a necessity and possibility because history is a process which extends the freedom of man over natural process to the point where universality is reached. It is an impossibility because man is, despite his increasing freedom, a finite creature, wedded to time and place and incapable of building any structure of culture or civilization which does not have its foundations in a particular and dated locus."

That is our task now. How do we find the motivation to accomplish it? Niebuhr again:

Nothing that is worth doing can be achieved in our lifetime; there we must be saved by hope.
Nothing which is true or beautiful or good makes complete sense in any immediate context of history; there 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 own standpoint.
Therefore we must be saved by the final form of love which is forgiveness."
