“And God spake unto Noah, and to his sons with him, saying, ‘And I, behold, I establish My covenant with you, and with your seed after you; and with every living creature that is with you, of the fowl, of the cattle, and of every beast of the earth with you; from all that go out of the ark, to every beast of the earth. And I will establish My covenant with you; neither shall all flesh be cut off any more by the waters of a flood; neither shall there any more be a flood to destroy the earth.’
And God said, ‘This is the token of the covenant which I make between Me and you and every living creature that is with you, for perpetual generations: I do set my bow in the cloud, and it shall be for a token of a covenant between Me and the earth. And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud: 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.’ And God said unto Noah, ‘This is the token of the covenant, which I have established between Me and all flesh that is upon the earth.'” Genesis 9:8-17 (KJB)
There is a major difference between God’s rainbow He placed in the clouds to remind Himself and Adam kind that He will never again destroy the earth by flood. The rainbow of man is flawed, and really speaks of a coming judgment upon the earth by fire; and it will come.
There is deliverance from the fiery judgment through Jesus Christ, and His sinless sacrifice of Himself, His burial, and resurrection. Believe on Him and be saved; be delivered from the imminent judgment, and eternal judgment. Repent and believe in Christ and His finished work.
