“As for you, be fruitful and increase in number; multiply on the earth and increase upon it.” Then God said to Noah and to his sons with him: “I now establish my covenant with you and with your descendants after you and with every living creature that was with you—the birds, the livestock and all the wild animals, all those that came out of the ark with you—every living creature on earth. I establish my covenant with you: Never again will all life be destroyed by the waters of a flood; never again will there be a flood to destroy the earth.” [Genesis 9:7-11]
Noah responded to God’s saving grace by building an altar. Those of us who have been saved from the wrath to come should likewise bring to God our heartfelt worship. It is an acceptable and pleasing today as it was in Noah’s day. The Lord made a covenant that He would never again curse the ground or destroy every living thing, as He had done; also, He would provide regular seasons as long as the earth endured.
The rainbow was given as a pledge that God would never again destroy the earth with a flood.
Again, God said to Noah and his sons:
“ I am going to make a solemn promise to you and to everyone who will live after you. This includes the birds and the animals that came out of the boat. I promise every living creature that the earth and those living on it will never again be destroyed by a flood.
The rainbow that I have put in the sky will be my sign to you and to every living creature on earth. It will remind you that I will keep this promise forever. When I send clouds over the earth, and a rainbow appears in the sky, I will remember my promise to you and to all other living creatures. Never again will I let floodwaters destroy all life. When I see the rainbow in the sky, I will always remember the promise that I have made to every living creature. The rainbow will be the sign of that solemn promise.”
“And God said, “This is the sign of the covenant I am making between me and you and every living creature with you, a covenant for all generations to come: I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. Whenever I bring clouds over the earth and the rainbow appears in the clouds, I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life. Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of every kind on the earth.” Genesis 9:12-16 ]
