Historians say the legend about a pot of gold at the end of a rainbow began with the Irish in Old Europe. Some say since you can’t reach the end of a rainbow to check it out, it can’t hurt to think it might be there. People all the world over have come up with various stories about the significance of the rainbow. But the most credible and important explanation comes from the Bible. After the flood, God tells Noah the rainbow would remind humanity that God will keep His word never again to destroy the earth with a flood. We read God’s promise in Genesis 9:14, “I have placed my rainbow in the clouds. It is the sign of my covenant with you and with all the earth. When I send clouds over the earth, the rainbow will appear in the clouds, and I will remember my covenant with you and with all living creatures. Never again will the floodwaters destroy all life.” The rainbow assures us of God’s faithfulness in keeping His word. Now that’s bad news for those who ignore what God says hoping to escape consequences. But it is very good news for those who rely on God’s promise never to abandon His child either in this life or the one to come.
