By my reading of the Scriptures of God, specifically all the ones I've cited and quoted here so far,
certain (fallen) angels sinfully and illegally reproduced with human females in the flesh.
In an evil and grotesque and illegal and condemned counterfeit of God's design----
to Himself "become flesh" which He did, through reproduction (although not 'sexual'),
by His Holy Spirit fertilizing and conceiving a human egg within Mary to produce the sinless GodMan,
ManGod, Jesus Christ, who is now not only God, but also human permanently, irrevocably, and eternally,
as our Husband and Head, for His enjoyment, satisfaction, and expression eternally, and increasingly
unto eternity.
The fallen angels, and all angels (cf Heb 1:4-14), do not, and have not, "become men." The worst those
particular evil ones could, and did do was to reproduce.........evil 'hybrids,' Nephilim. Neither I, nor the Bible,
said that those principalities "became men." As far as "struggling" with lust, that also appears to misrepresent
both the Bible, Genesis 6, and me. The fallen angels had already rebelled, and fallen, before God created Adam,
before He created man. So they were actively rebelling and attacking God and God's purpose by seeking to corrupt
mankind. The situation at Noah's time was at least the "third" fall of man recorded in Genesis.
Lastly, the dear poster questioned or opined that "somehow they overcame that problem?"
Lol, I question your question. What do you mean? Those Genesis 6 angels, according to my reading of Peter and Jude,
were judged very soon after by the Lord, being chained in Tartarus. (Much like Satan, a fallen angel, himself will be
chained in the unpleasant part of Hades for 1000 years.) So the Genesis 6 angels didn't "overcome" their "problem."
They're locked away from human women! And all or most other fallen angels are.............deterred. By this divine "criminal
justice system." The poster mentions "demons." Which are another, separate, group of fallen beings allied with Satan.
Demons are not angels, nor men. Never were, never will be. Though the word "spirits" is also applied to them.
