All of that aside, let's at least try and determine logical reasons why God would equip angels with the ability to procreate with humans, meaning women in this case, if He never wanted them to do that at anytime ever. I can't think of any myself. Can you?
Just like the time gap between Gen 1:1 and 2 where God left out all detail of how and why the earth became "tohu", we aren't given any information about why some angels co-inhabited with females.
One thing to keep in mind, though, is that God is omniscient and always knew everything that would occur, so what certain angels did wasn't a surprise to Him.
Do angels still have this capability? And if yes, what is preventing them from doing this again?
God, obviously. Recall that all demons obeyed Jesus and in Job, Satan, the leader of the rebellion was limited by God's word. When God said "don't touch the man" in ch 1, he didn't. In ch 2 all God said was "don't kill him", which he didn't.
So all it takes is a direct command from God and every angel obeys directly.
It's not like there are not plenty of fair women out there these days. They are already doomed anyway, what would they have to lose if they were to do this again?
Not the point. When God commands an angel to NOT do something, they DON'T.
And what about what Jesus said in Matthew 24? If one interprets some of Genesis 6 like some of you are, shouldn't this mean angels will start mating with earth women again and producing offspring?
What is there in Matt 24 that relates to Genesis 6 that you note?
Matthew 24:38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,
Now compare some of this with what is recorded in Genesis 6.
Genesis 6:2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
Which led to this---when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown(Genesis 6:4).
If Jesus is comparing to Genesis 6 in Matthew 24:38, which He obviously is, and indicating it will be like those days, how could it be like those days if those days in Genesis 6 led to literal angels marrying earth women, then producing literal offspring, but what is recorded in Matthew 24:38 is meaning something entirely different altogether, in regards to marrying and giving in marriage?
It seems to me then, one should interpret Genesis 6, in regards to marrying, the same way they interpret it to mean in Matthew 24:38. IOW, if nothing in Matthew 24:38 involves literal angels marrying earth women, then producing offspring, then neither does it literally involve any of that in Genesis 6 either.[/QUOTE]
