A Quote by Reinhold Niebuhr on acceptance, change, church, courage, god, grace, popularity, prayer, serenity, and wisdom

God, give us grace to accept with serenity the things that cannot be changed, courage to change the things which should be changed, and the wisdom to distinguish the one from the other. This prayer was first printed in a monthly bulletin of the Federal Council of Churches and has become enormously popular. It has been circulated in millions of copies.
