The Difference Between Noah and the People of His Day

The People
Lustful – Genesis 6:1,2
Half-Breeds – Genesis 6:1, 2, 4 (Nephilim were people bred from angels (sons of God) and human woman. https://youtu.be/FC8wWsBKc88
These half breeds corrupted the human genome so much that Jesus could not have come. This is one of the main reasons for the flood.

The second main reason is found in verse 5: The LORD saw how great the wickedness of the human race (not just men but women) had become on the earth, and that every inclination of the thoughts of the human heart was only evil.

This verse shows that all people thought about was how to do wicked and evil deeds. They did not believe in God anymore. Not that they did not believe there was a God but that they turned their backs on God. The biggest sin was that of unbelief

Noah
But Noah found favor in the eyes of the Lord vs 8. Why???
Noah was righteous, blameless among the people of his time, and he walked faithfully with God. This does not mean he was sinless but that he believed in God, believed God and obeyed God to the best of his ability. He taught his wife and children that. He preached that to the people of his time. 2 Peter 2:5 It was his faith that saved Noah and his family. Hebrews 11:7
