It is generally understood that the creator of person, place, or thing has the right to name and establish its purpose.

So who determines what a rainbow represents?

Genesis 9:8-17 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.

After God had judged the world for the greatness of their sin before Him, He made a covenant with man that he would never destroy the earth again in its entirety with water and signified it with a rainbow.  The rainbow was a consolation to mankind that although water can be feared for its devastating effects it can also be considered a blessing.  So we see that the rainbow was a promise that God would not judge this world by completely covering it with water again.

The meaning of the rainbow has been changed in the world today.  One of the major sins of the Bible is sexual impurity.  It condemns divorce (putting away), adultery, fornication, and sodomy.  Many committed these sins throughout the Bible, and God was patient in His judgment.  He has always given man a space of repentance because he is a gracious and loving God.  However, when that determined period of time is up there will always be judgment.

Sin is wrong no matter what!  Why do people take the promise of the rainbow and use it for a symbol of that which God condemns?  Are they challenging God that they can do what they want, and He will do nothing about it?  Are they making a statement that He has no power and will not judge sin?  God will judge ALL sin including the sin of sodomy, but thankfully He is willing to forgive sin to the one that will repent.  Repentance is turning from that which is wrong and turning to that which is right.  I am afraid that the rainbow has become a diabolical statement that people will not repent of their sin.

The sins and attitude towards those sins are being revealed in the United States of America and the world.  Our supreme court, our president, some of our governors, some of our citizens, etc. are waging a war against the principles of God in more ways than one and declaring that people with right principles are haters.  Hate is found when someone rejects the God of love (Jesus Christ) and seeks the lusts of their own heart and mind.  What is in men’s hearts and minds is being revealed.  Yes, God knows the heart, and He does not see good people.  However, Jesus said in Luke 5:32, “I came not to call the righteous, but sinners to repentance.”

Romans 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.   Saved from what?  The coming judgment of ALL SIN.
