Genesis 6:12

And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. These statements complete the picture drawn in verses 1-4. Utterly corrupt was the earth before the face of God, like a rotten piece of meat whose very appearance is nauseating. It would have been impossible to hide the conditions from the Lord; He was compelled to intervene with His curse and punishment, because the earth was full of violence and open wickedness. The Lord was a witness of the growing, unspeakable corruption which finally included the entire human race, carnal-mindedness being the governing impulse of every man's life. All that men had before them and wanted to keep before them was the gratification of their own fleshly desires. Their wickedness was openly perpetrated, and their moral judgment, their conscience, was submerged in their approbation of everything that was evil and corrupt.
