That is a speculative answer. The bible never says immortal bodies do not need procreation for the sake of repopulation.
That again is speculation. Adam's body was immortal. He did not have to go the tree of life to live forever UNTIL AFTER HE SINNED. Eating the fruit was not said to allow him to live forever and after Adam sinned, and death was inflicted upon him due to sin.
You say the earth is not for the sons of God, but where does the bible say that?
When we died we are absent from the body and present with the Lord.
2Co 5:6-8 KJV Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord: (7) (For we walk by faith, not by sight
(8) We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.
Bodies, immortal or mortal alike, are earth-suits, really. If we are absent from body and present with the Lord upon death, we are in Heaven. That means we do not require bodies to be in heaven. Bodies are not made for heaven. Heaven is not a physical place where one needs a physical body to interact with it. You cannot show me a map of the physical universe and point at certain coordinates in the physical realm and say this is where Heaven is.
Eternal means no beginning nor any end. Not just no end like most people assume it means. So, we will never be eternal. We had a beginning. Only God is eternal. NOTHING ELSE. He gave us eternal Life when HIS LIFE was given to us. That alone is eternal.
But we shall live forevermore. So, what I mean is that we are only in heaven until the resurrection when we shall reunite with our immortalized bodies. And those bodies are made for the physical universe, not heaven. No where does the bible say we shall dwell in heaven forever. Yes, it's in dozens of hymns, but where is it in the bible? Where does the bible say our eternal home is heaven? No where. It is a false tradition. No biggie, really, but still false.
The only thing it says about forever is being with Jesus.
1 Thess 4:17. But it does not say Jesus is stuck in heaven forevermore. Wherever He is, there we will be. But it did not say it was heaven.
You say it is hypothetical to believe Adam was meant to remain and rule on earth forever and not die and go to heaven? It is hypothetical for you to say Adam's body was not immortal until sin! It is hypothetical for you to say immortal bodies are not involved in procreation due to lack of need for people who never die. All you said about that was hypothetical.
So what if God knew Lucifer would sin? In fact, technically, Lucifer is not even known to be the devil by what scripture says. That is hypothetical. Many claim he was a Babylonian king. I tend to agree Lucifer is the devil, but just saying. No where does it say that Adam was not intended to remain on earth forever because God knew he would sin. No where does it say God did not plan for Adam to remain on the earth in the Kingdom He put Adam in over the world because God knew man would sin and would later die and go to Heaven to remain forever.
In fact the most logical way to read scripture and make conclusions is to go by what it said, add nothing to it, and let what it said leave us with what was intended. And if God put Adam in the earth to rule over it to live forever on it, that is the will of God for us in the future, to get us back on track from where Adam fell.
Adam was not in heaven when he fell and requiring restoration for mankind to die and go to heaven and be there to continue what what God planned for humanity. Adam was on earth! Earth was made for MAN. You think God is going to discard the physical universe that makes man look like less than the size of an element of an atom in comparison, just because God planned it to be temporal since he foresaw man sinning?
If there is a physical new heaven and earth, the fact remains there is a physical to endure forever, even if it is NEW and NOT YET. And THAT is what our physical BODIES were made for.
Incorrect.
Nothing says Adam REQUIRED the fruit of life
to physically live forever before he sinned. It only mentioned that after he sinned, and
Romans 5 said sin brought death.
They can never be eternal. Immortal means "never dying". That is not temporal. The things we see now are temporal only because they stand as they are AFTER SIN.
That is hypothetical.
