Genesis 6:5

And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. Noah's preaching had little or no effect. Jehovah saw that in spite of all His efforts to win the hearts of men the wickedness of man in general was increasing. No dam was able to hold back the flood of evil: the entire human race persisted in its mad course toward destruction. Every thought that took form in the heart of every man was wicked all the day long; every one of them was an adept in every form of vice, and all the planning of their hearts was ever directed to that which challenged the righteousness of God.
