Oh, you mean the good angels. I guess they can be whatever the Lord wants them to be for his purpose at the time.
But you boxed yourself in now. Because if you are saying those were sons of God, you are saying they were the good angels. You can’t have it both ways. Sons of God having sex with humans in Genesis 6, obvioiusly the bad angels...and suddenly you have sons of God or angels not having sex with Sodom folks.
So are Sons of God good or bad?
I’ll let someone else explain it to you. I’m shutting down for the day.;-)
Both.
