God said to Noah and his sons and said to them: Be fruitful and multiply and fill the earth…See I am now establishing my covenant with you and your descendants after you with every living creature that was with you: the birds, the tame animals, and all the wild animals that were with you – all that came out of the ark. I will establish my covenant with you, that never again shall all creatures be destroyed by the waters of a flood; there shall not be another flood to devastate the earth. 

Genesis 9:1, 9-11

Just as with Adam, God tells Noah to be fruitful and multiply. Through Noah, humanity has been given a second chance to start over in the world. The rainbow serves as a covenant that God will not send another flood. It also serves as assurance that God will not handle the problem of human evil in the same way radical way again.

Thank God today that he is a God of second chances.
