You are assuming this….are you saying that it is impossible for God to recreate what he has already made?
No, I'm not saying God can't recreate something that He has already made. He created many animals and plants, not just one of each (it was only man, and woman, that God created just one of). I believe that if God wanted to He could destroy the whole universe and create a new one (or as many universes as He desires). I never assume that God is limited in any way.
I am not
assuming that if we die and perish that when God recreates us He would be creating a clone; I am
reasoning that that would be the case. If we perish in a fire, or if we simply perish in a grave (eaten by worms and insects, with perhaps only bones left remaining, though bones would eventually disappear too), then we could not be resuscitated, because there is nothing to resucitate and bring back to life. God can create an exact copy of our previous body, and he could program our brains with our memories and character, etc., but it would just be a copy and not the original us. It only makes sense to me if humans have an invisible spiritual part that is not destroyed at death (because it is not physical), that can be awakened to a conscious state by God and placed in a body, whether a new (different) body in the resurrection or in the restored original body that was dead and decaying in the case of the miracles performed by Jesus, prophets and apostles of raising people from death within days of them dying.
Hence when the Scriptures, including Jesus' own words, say that the dead are sleeping and will be awakened, it cannot be referring to the physical body, which returns to dust, but it is referring to the spritual part which remains in God's care. Ecclesiastes 12:7 (WEB):
(7) and the dust returns to the earth as it was, and the spirit returns to God who gave it.
The Jewish Targum paraphrases this verse as, “The Spirit will return to stand in judgment before God, who gave it thee”. Therefore the Jews seemed to understand the spirit to be the essence of who we are, and not just our breath (our breath can't stand in judgement).
Who said we would be clones? If our personality is restored, then we as a person will return to life….
An analogy would be a computer. The physical body is represented by the computer, and our personality, knowledge, memories, etc. is represented by the software, which is not physical. If the computer is destroyed, or perishes in a fire, etc., then the computer can be restored by replacement hardware and a backup of the sofware can be retrieved from the safe and copied onto the computer. It would then behave just like the original computer, but it isn't the original computer, it's just a copy. The software could be copied onto many computers, each of the same or different specification, but they would all be copies. If the computer was just the hardware, and that perished, then that computer could never be restored - a computer without the sofware is not a computer, it's just a heater. The sofware backup in the safe is not functioning, similarly after death our spirit is not functioning, it remains in God's safe. At the resurrection God takes the spirit from His safe and places it in a new body, but the difference from the analogy is that there is only one spirit, that was living but then in a dormant state (death), which God restores to a living state and give it a new body. Like you I don't know the science of how God can do that, but I believe that He can and will do it.
The spiritual part of us goes back to God who remembers everything about us…our life choices and what motivated us to do what we did in the lifetime we had……it is stored in his memory, ready to be reinstalled in a new body.
Now you are assuming that our personalites are just preserved in God's memory. That means there is no continuity between our current lives and our resurrected lives. The resurrected person would just be a copy, and not us.
Those in the grave are like those in a state of suspended animation…..their absence is temporary
That's not a good analogy for your understanding, because in suspended animation the animal still exists and is awakend from it - coming out of suspended animation doesn't involve creating a new animal, it's the same 'sleeping' animal that awakens, like our same spirit sleeping and being awakened from sleep. As Jesus said before he raised Lazarus from death, John 11:11 (WEB):
(11) ... he said to them, “Our friend, Lazarus, has fallen asleep, but I am going so that I may awake him out of sleep.”
Paul also talks of how "we" live in a "house", which is our human body, but when we die and that body is dissolved then "we" will be given a new house by God (some time in the future) - an immortal spirit body (if we are a Christian). Consider 2 Corinthians 5:1-10 (WEB):
(1) For we know that if the earthly house of our tent is dissolved, we have a building from God, a house not made with hands, eternal, in the heavens.
(2) For most certainly in this we groan, longing to be clothed with our habitation which is from heaven;
(3) if so be that being clothed we will not be found naked.
(4) For indeed we who are in this tent do groan, being burdened; not that we desire to be unclothed, but that we desire to be clothed, that what is mortal may be swallowed up by life.
(5) Now he who made us for this very thing is God, who also gave to us the down payment of the Spirit.
(6) Therefore we are always confident and know that while 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 courageous, I say, and are willing rather to be absent from the body, and to be at home with the Lord.
(9) Therefore also we make it our aim, whether at home or absent, to be well pleasing to him.
(10) For we must all be revealed before the judgment seat of Christ; that each one may receive the things in the body, according to what he has done, whether good or bad.
