If the supernatural view of the first part of Genesis 6 is taken, where it's Angels making human hybrids and not this kinda goofy redundant view that it's just men.. cause if it is just men then it's men reproduced, had daughters and then.. men saw them and took them as wives and reproduced? Wait isn't that how they got the daughters in the first place?
But anyway.. if it's true that it's Angels with Humans reproducing that made the Nephilim,
#1 it lends credence to I Enoch, which Jude, and Peter reference, Jude directly quoting, and Jesus appeared to reference in Matthew 22 (there is NOWHERE in the canon old testament that indicates marriage doesn't exist after the resurrection, but I Enoch gives the same rationale for there not being marriage after the resurrection as Jesus gave... even though it's a difficult thing to take in and kind of makes little sense as women, marriage and procreation were introduced BEFORE the fall, not after, but the rationale of no marriage and no procreation because no death is hard to reconcile with there not being death until the fall but marriage existed before the fall)
#2 It challenges very popular beliefs such as, simply seeing God's glory eliminates all desire for anything like sex or children, just staring at God fulfills all desires. Popular teaching but, if Angels who lived in Heaven and beheld God in all His glory chose to "leave their first estate" to marry human women and have children... why wouldn't we? If God's glory was all we'd ever need, why'd God provide other things and other gifts? Angels were created just to glorify God, and God never gave them things like food, a planet, animals, women, etc. So if any being would be totally fulfilled by God's glory, and desire nothing else.. it'd be Angels... but they still chose other things, they still chased after "strange flesh". Meanwhile we were given many other things, and given desires for those other things, to be fulfilled by things other than staring at Jesus. Praising God doesn't satiate hunger or thirst drive for instance, God PROVIDED the means to satiate them instead.
#3 It also challenges the popular belief that the elimination of sin in the New Earth is accomplished by beholding God's glory wiping away desires for anything else. If Angels can sin, after knowing God's glory but choosing something they didn't even have a biological need for.. wouldn't we also still have that potential, having been designed with needs that are fulfilled by providence rather than directly by beholding glory? Like we're already predisposed to choosing to satiate a need rather than just staring at God and praising Him. Resurrected Jesus still .. ate food for instance, and the imagery given even in Revelation 21 and 22 still involves eating and drinking, biological drives that are fulfilled through
things that God provides, rather than just, glory.
What prevents us from desiring physical intimacy from the opposite gender when even Angels desired it?
Does God just.. make us all Barbie and Ken dolls so we're physically incapable?
Does God change all women into men? I mean after all, only the male gender is really addressed in the later chapters of Resurrection aside from the bride imagery, the New Jerusalem is referred to by feminine pronouns, but the individuals, the overcomers, are referred to by masculine pronouns only.
Revelation 21
6 And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
7 He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
Mind you I don't believe that's how it's solved but I do have to pose the question of possible ways for it to be solved, because Angels choosing women over God's glory challenges the popular belief.
Most other sins can be addressed just by living in love, God's providence, and the impossibility of dying. Why bother stealing if God gives all things freely? Why bother coveting if God has provided for all needs? Can't murder when nobody can die, can't commit Adultery if there is no marriage, and can't lie if everyone already knows the truth.
But fornication.... that's a tough one to solve unless the people are physically incapable due to being anatomically incomplete, or there are no such thing as women anymore to desire, or the law itself changes... because the desire for physical intimacy exists often as a RESULT of loving someone, and no that desire is not created just out of biological need to reproduce, eliminating the possibility of biological reproduction does not eliminate sexual desire. Old people past menopause still have that desire, sterile couples still have that desire, and if Angels who were never created to have that desire or biological drive could learn to desire it... new biology doesn't solve it, living in love doesn't solve it, and if God's not providing a means for it, then it becomes an unmet desire, as it was an unmet desire for the Angels, and so they thought to fulfill it on their own.
