14 And when I shall cover the sky with clouds, my bow shall appear in the clouds: 15 And I will remember my covenant with you, and with every living soul that beareth flesh: and there shall no more be waters of a flood to destroy all flesh.
16 And the bow shall be in the clouds, and I shall see it, and shall remember the everlasting covenant, that was made between God and every living soul of all flesh which is upon the earth. 17 And God said to Noe: This shall be the sign of the covenant which I have established between me and all flesh upon the earth. 18 And the sons of Noe who came out of the ark, were Sem, Cham, and Japheth: and Cham is the father of Chanaan. 19 These three are the sons of Noe: and from these was all mankind spread over the whole earth. 20 And Noe, a husbandman, began to till the ground, and planted a vineyard.
21 And drinking of the wine was made drunk, and was uncovered in his tent. 22 Which when Cham the father of Chanaan had seen, to wit, that his father's nakedness was uncovered, he told it to his two brethren without. 23 But Sem and Japheth put a cloak upon their shoulders, and going backward, covered the nakedness of their father: and their faces were turned away, and they saw not their father's nakedness.
Every now and then after it rains we are graced with the beauty of the rainbow. It doesn't happen all the time but only when the sun shines. Science will say it's due to the refraction of light, but God still created it in the first place. It's his constant reminder of the covenant he made with Noah. We have to remember that the rains had stopped and after a period of time the waters had gone down in order for them to leave the ark. When they received the bow in the sky it was by God's hand. We still receive it ourselves when we see it as a reminder of his covenant. A glorious symbol of his love for us. I don't question what was written in regards to how he made it all happen because I love him enough to believe in the truth of what has passed on from generation to generation. His eternal covenant of love for mankind.
