"When the people of Nineveh believed God; they proclaimed a fast and all of them, great and small, put on sackcloth. When the news reached the king of Nineveh, he rose from his throne, laid aside his robe, covered himself in sackcloth, and sat in the ashes." Jonah 3:5, 6
Nineveh repented and God forgave them. How simple the answer to America's problems. Repentance.
God forgave them. Sorrow for one's sins draws down mercy. Even the king humbled himself. Maybe we should learn a few things from the past instead of constantly reliving it.
