Genesis chapter 6 tells us that before the Flood invisible sons of God, angels, left their rightful position in heaven, materialized human bodies and married women on earth. They brought forth a hybrid race, their progeny being called Nephilim, meaning, most likely, “fellers” or “those who cause others to fall down.” Since their coming to earth was out of harmony with God’s purpose, it could hardly be expected to result in good, nor did it. An increase in violence, in keeping with the meaning of the name Nephilim, was the direct result. Yes, disobedient heavenly sons of God on earth were chiefly responsible for the upsurge of crime and violence in pre-Flood days.

The angels of Noah’s days left heaven and came down to the earth of their own choice; the Devil and his demons in this time of the end have had no choice in the matter. They were simply evicted! The angels of Noah’s days were able to materialize human bodies on earth to enjoy illicit pleasures; the Devil and his demons in this time of the end have been unable to do so.
