God made a covenant with people, creatures, and the earth that he would never drown it again. God was serious and repeated that promise over and over again. I found it fascinating that the covenant was also with the animals and every living creature of all flesh, not just man. That shows us how much he values his creation, so much so that every time it clouds up or rains, a rainbow appears in the sky as a reminder of that promise; it's not only for us but for God. It is an everlasting contract. The rainbow is sacred and holy and should be respected by all. It is a precious gift that is humbling; that the creator of all things thought it necessary to assure us of his commitment by giving us a beautiful sign. When you see it in the sky, thank God for valuing our lives.
And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh. And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth. Genesis 9:15-16
