What argument(s) convinced you that Genesis 6:1-4 did NOT discuss fallen angels mixing it up with human females?
Oh, are we doing fallen angels now?
What Q post is that one? I missed it.
Reading and studying the Bible as an integrated peice thta points to Jesus Christ and shows us who God is as He tells us in the Word. An explanation of the words used for sons of man and the sons of God, the physical capabilities of angels which would preclude them from reproduction, understanding Genesis and how the division between those who believe God and those who reject God. The angel teaching is exciting but I think the real truth is much more understandable and believable. Mighty men of God are also referenced in OT as dedicated warriors, faithful servants, etc.
