Who were the Sons of God in Gen. 6:1-4?
Angels or the Godly line of Seth?

1. Angels are referred to as "Sons of God" Job 1:6; 2:1; 38:7

2. II Peter 2:4-5

3. Jude 6-7 note to connection to Sodom and Gomorrah and their sexual sin and "strange flesh."

4. The angels from the fall of Satan are demons and these in Gen 6 are confined to be released in the tribulation period.

5. Jesus said angels don't marry in heaven but he did not say they can't reproduce in a human body.

6. You would not get giants from humans reproducing, if the giants came from the Godly line of Seth and the line of Cain.
