11 In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened. 12 And rain fell upon the earth forty days and forty nights.
The Holy Bible: English Standard Version. (2001). (Ge 7:11–12). Wheaton: Standard Bible Society.
God told Adam in the Garden that the ground itself was cursed because of Adam’s sin.
In the two thousand years between Adam and Noah, sin polluted everything and everything had to be destroyed.
But pay attention to how it happened. In Genesis 1, God had ordered the earth, separating waters into heavens and earth, then separating the waters on the earth into seas and waters below the earth.
Here, 2000 years later, all of creation comes undone. The waters break forth from the deep and fall from the heavens. The orderly creation God established in Genesis 1 is completely upended. The very planet is reverted back to Genesis 2. All that remained was light and darkness and even the light is blotted out by storm clouds.
Why? Man’s sin affected the earth that dramatically.
We think of most sins as small things. But the accumulation of those small things disordered an orderly creation. Think about the magnitude of that.
But then consider this. God preserved one man and his family for that one man being righteous. The family survived not because Noah was not a sinner, but just because he worked to order his life for God. Even in the undoing of creation, the order becoming disordered, one man ordering his life toward God continued to exist and humanity was spared complete annihilation.
