Genesis 8: 20-22

20 And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.

21 And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done.

22 While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.

Genesis 9: 11-17

11 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.

12 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:

13 I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.

14 And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud:

15 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.

16 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.

17 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.

 

Unless you're a secularist douchebag, there's no denying that the Lord promised Noah and his descendants that the world shall not be destroyed by God because of mankind again.
