This double rainbow appears once a day in our home and serves to remind us of God's promise:
Genesis 9:11-13 This is my promise to you: All life on the earth was destroyed by the flood. But that will never happen again. A flood will never again destroy all life on the earth.” And God said, “I will give you something to prove that I made this promise to you. It will continue forever to show that I have made an agreement with you and every living thing on earth. I am putting a rainbow in the clouds as proof of the agreement between me and the earth.
