The rainbow

Every person will see a rainbow in the sky. When it rains then you will see an rainbow. Many people will think this. Why is there is rainbow in the sky? If the person don't read the Bible then that person will not understand know this fact.
The rainbow is a promise to Mankind. God promise that there will not be a second world-wide flood.
God understands that mankind is wicked but the world-wide flood is not an option. He give grace to people.
The love of God should make people to God. We deserve God's judgement.
There should be a balance teaching. God is love and grace, when you see the rainbow but one day this will happen.
The second coming of Jesus will bring judgement on this world. But God doesn't want to anyone go to hell.
A person can walk on the bridge. The cross of Jesus is the bridge between man and God. We can accept the righteousness from God and experience God. We need to repent from our sins.
A person can experience  the God that created the rainbow.

Genesis 9:8-17

⁸ Then God said to Noah and to his sons with him: ⁹ “I now establish my covenant with you and with your descendants after you ¹⁰ 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. ¹¹ 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.”
¹² 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: ¹³ I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. ¹⁴ Whenever I bring clouds over the earth and the rainbow appears in the clouds, ¹⁵ 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. ¹⁶ 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.”
¹⁷ So God said to Noah, “This is the sign of the covenant I have established between me and all life on the earth.”
