The rainbow is the perfect example of how God left signs of love for us to enjoy & share with him and then having been deceived by satan on earth to confuse us.
So that people would vilify it unknowingly the true meaning behind Gods creation of the rainbow with 7 colors in the sky.
and satans creation of the rainbow through corruption of man with 6 colors that's on clothes & flown as flags now to mock God.
And God said: “This is the sign of the covenant which I make between Me and you, and every living creature that is with you, for perpetual generations:
I set My rainbow in the cloud, and it shall be for the sign of the covenant between Me and the earth.
It shall be, when I bring a cloud over the earth, that the rainbow 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;
the waters shall never again become a flood to destroy all flesh. The rainbow shall be in the cloud, and I will look on it to remember the everlasting covenant between God and every living creature of all flesh that is on the earth.”
And God said to Noah, “This is the sign of the covenant which I have established between Me and all flesh that is on the earth.” Genesis 9:12-17
