There is no such idea written about angels or any heavenly being in an asexual state. That idea is certainly nowhere written in God's Word!I do not agree Davy.
You said...........
"Angels are sexless, spiritual created beings, who when took on physical forms always appeared as males, but are not human!"
Was that a slip up?"
Genesis 6 is speaking of MEN not angels. Angels are a-sexual and can not mate with anything much less human women.
"Sons of God" in Genesis can NOT in any way be angels!!!!!
I Job 1:6.......those SOns of God ARE angels as the LOCATION is in heaven and there were NO MEN in heaven then!
Matthew 22:30 clearly says that everything in heaven is asexual. That includes the saints who are there now, the church that will be later and the ANGELS who have been there since their creation.
Angels do not reproduce...they were created.
Want to know where that asexual idea for the angels originated? It comes from pagan Androgyny. They believed that 'both' sexes were involved in God's creation of heavenly beings.
That pagan belief even crept into the Roman Church early on, as they do believe in female angels.
All angels have the outward appearance of men, as written in all Bible examples. This is even why the "sons of God" title is applied to women in Christ too, pointing to the the spirit state in the world to come.
What you are not understanding is about 'spirit'. That is NOT simply about ghosts. Nor demons.
Per Hebrews 4:12, we each have a 'spirit' inside us, and our soul is attached with it. At death of our flesh our spirit with soul leaves our flesh (Ecclesiastes 12:5-7; Matthew 10:28). Our spirit and soul are NOT made up of flesh matter. Our spirit is about another body Apostle Paul in 2 Corinthians 5 said we have if our flesh body were dissolved. It is the "spiritual body" he was declaring for the resurrection body type in 1 Corinthians 15. The idea of 'soul sleep' is an old Jewish theory based on their understanding of Genesis 2:7. They believe the soul is made up of flesh, when it is not. So they think our soul dies with our flesh body and must be resurrected along with our flesh. That is not what The New Testament Scriptures reveal at all.
Thus our 'spirit', or spirit body, is of that other dimension of God's creation, the heavenly. It's simply a body type for the heavenly dimension, that's the easiest way I can say it. That means it has a form and likeness that originates in the heavenly, which is from God's Own outward likeness and appearance. It would appear the way you are thinking of the idea of 'spirit' is like ghosts or demons, not understanding that other dimension of existence.
