“I know you are asking today, ‘How long will it take?’ I come to say to
you this afternoon: however difficult the moment, however frustrating
the hour, it will not be long, because the truth pressed to earth will
rise again. How long? Not long, because no lie can live forever. How
long? Not long, because you will reap what you sow. How long? Not long,
because the arm of the moral universe is long, but it bends toward
justice.”
- MLK, from the speech at the end of the Selma march.
