If we will keep our bodies. But a transformation in our bodies will take place. The Bible doesn't say much detail about it but basically, it's indestructible. If we cannot die then there's no need to reproduce. The role of reproduction is to perpetuate our species. If immortal then what's the point of reproduction, the effect will not be sustainable and even detrimental to the Universe.
Now why would reproduction be detrimental to the universe? I studied the verse concerning angels not being married nor given in marriage and it says that the angels are not married nor are they engaged to be married, in other words they are SINGLE. The woman would not be married to any of the seven men because death has nullified her covenant of marriage with them. I'm by no means saying that the angels in heaven are allowed to marry but they are quite capable of having sex with women and reproducing, Genesis 6 states this as a biblical fact in history!
I am also well aware that this has been explained as the sons of God being the sons of Seth who were the followers of God but the bible does NOT say that. They produced hybrids the Nephilim or giants, men of renown or men of great ability and strength. My point here is that being "like" the angels, being spiritual beings will not eliminate our ability to have sex or reproduce. But why? What would the purpose be for spirit beings to reproduce? To fill the whole creation, the entire universe of endless galaxies and endless solar systems and endless planets with endless perfect, sinless children of God, God beings. God says that when Christ returns and the faithful are resurrected (or changed for those that are alive at His coming) as the first fruits and we will be like Christ, children of God and brothers and sisters of His first born Son. The bible says of the increase of His government there will be no end, it will spread out from earth to the vast endless universe. We are the FIRST fruits the greatest harvest comes after and just as the creation has no end planting and harvesting will have no end.
I believe that we will marry again for eternity, I also believe that the bible means what is says about Christ marrying but it's not to all of us or to the New City of Jerusalem, these are allegories, but to one woman who has made herself ready through the Spirit of righteousness. At the resurrection we will be a new creation, new beings with Christ, who having gone before made a path for us to become as He is literally. Living spirit beings who can become flesh and bone, eat and drink and become spirit again at will. The bible is filled with spirit beings appearing as physical beings. If you think it's not possible for spirit to become flesh or to impregnate think again, this is what God did to Mary but without a sexual relation. He did it in-vitro.
As far as the angels that had sex with woman and they became pregnant the problem there was they were not supposed to! Only God the Creator has the ability to combine Spirit with flesh and blood to produce a perfect child and He only did it once. But God allowed it. The offspring of the angels were distorted mentally and physically but in many ways superior to human beings. But they were vile in thoughts and deeds and are the originators of mankind's perversions. Noah was saved from the flood because he was perfect in his generations, his blood was not mixed with the fallen angels or their children.
I did not come to these ideas without much prayer, research and study of the Word of God and sound reasoning. Prove what you're told whether it is of God or not.
