Hey look that sign in the sky saying God would never have a local flood again!
Gen 9: “And God said, “This is the sign of the covenant that I make between me and you and every living creature that is with you, for all future generations: I have set my bow in the cloud, and it shall be a sign of the covenant between me and the earth. When I bring clouds over the earth and the bow is seen in the clouds, I will remember my covenant that is between me and you and every living creature of all flesh. And the waters shall never again become a flood to destroy all flesh. When the bow is in the clouds, I will see it and remember the everlasting covenant between God and every living creature of all flesh that is on the earth.” God said to Noah, “This is the sign of the covenant that I have established between me and all flesh that is on the earth.”
Notice it says “the waters shall never again become a flood to destroy ALL FLESH.”
Which is parallel to “the everlasting covenant between God and EVERY LIVING CREATURE OF ALL FLESH THAT IS ON THE EARTH”
You can not be a “local flood” guy and take the bible seriously. The bible is not unclear or ambiguous about Noah’s flood destroying the world – covering the whole earth.
Gen 7:4 “For after seven more days, I will send rain on the earth forty days and forty nights; and I will blot out from the face of the land every living thing that I have made.”
Gen 7:17 “Then the flood came upon the earth for forty days, and the water increased and lifted up the ark, so that it rose above the earth. The water prevailed and increased greatly upon the earth, and the ark floated on the surface of the water. The water prevailed more and more upon the earth, so that all the high mountains everywhere under the heavens were covered.”
Gen 7:21 “All flesh that moved on the earth perished, birds and cattle and beasts and every swarming thing that swarms upon the earth, and all mankind; of all that was on the dry land, all in whose nostrils was the breath of the spirit of life, died. Thus He blotted out every living thing that was upon the face of the land, from man to animals to creeping things and to birds of the sky, and they were blotted out from the earth; and only Noah was left, together with those that were with him in the ark.”
II Peter 2:5 “and did not spare the ancient world, but preserved Noah, a preacher of righteousness, with seven others, when He brought a flood upon the world of the ungodly;”
Isaiah 54:9 “”For this is like the days of Noah to Me, When I swore that the waters of Noah Would not flood the earth again; So I have sworn that I will not be angry with you Nor will I rebuke you.”
II Peter 3:5 “For when they maintain this, it escapes their notice that by the word of God the heavens existed long ago and the earth was formed out of water and by water, through which the world at that time was destroyed, being flooded with water. But by His word the present heavens and earth are being reserved for fire, kept for the day of judgment and destruction of ungodly men.”
Luke 17:26 “And just as it happened in the days of Noah, so it will be also in the days of the Son of Man: they were eating, they were drinking, they were marrying, they were being given in marriage, until the day that Noah entered the ark, and the flood came and destroyed them all.”
