So Deeje, is only half right about the resurrection in the 1000 years. There are two forms of resurrection in JW theology, those of the anointed and those of everybody else. The first resurrection is already happening. The anointed are raised immediately from death to perfection. I forgot to distinguish between which in my post.
Also, if defects of the body are removed, and diseases are often on a genetic level, then the body has to be edited. Regarding your point about new cells, the cells are new but the DNA isn't changed, therefore one with genetic diseases still retain those diseases. I am talking about change on a DNA level, which is genetic modification.
OK. Lets see what you guys say:
Regarding the anointed who are raised to heaven:
“How Are the Dead to Be Raised Up?” | Watchtower Study (jw.org)
Under "What sort of body?"
"8. What illustration can help us to understand the resurrection to heavenly life?
8 When someone dies, his body decomposes. But the One who created the universe from nothing can resurrect that person,
giving him a suitable body. (
Gen. 1:1; 2:7) Paul used an illustration to show that God would not need to bring back the same body. Think of “a bare grain,” or a plant “seed.” A seed of grain that is planted in the ground germinates and becomes a new plant. The resulting plant is quite different from the small seed. Paul used this comparison to show that our Creator can provide “a body just as it [pleases] him.”"
10. How might differences in bodies relate to the resurrection?
10 Note what Paul said next: “So it is with the resurrection of the dead. It is sown in corruption; it is raised up in incorruption.” Of course, upon dying, the human body decays and returns to the dust. (
Gen. 3:19)
So how can it be that a body is “raised up in incorruption”? Paul was
not speaking of a human who is resurrected to life on earth, such as those raised by Elijah, Elisha, and Jesus. Paul was referring to a person who is resurrected with a heavenly body, that is, “a spiritual one.”—
1 Cor. 15:42-44."
"12 Paul was reaching the climax of his discussion of the resurrection. It is important to note that Jesus was not resurrected with a human body. Paul pointedly said: “Flesh and blood cannot inherit God’s Kingdom” in heaven. (
1 Cor. 15:50) The apostles and other anointed ones would not be resurrected to heaven with corruptible bodies of flesh and blood. When would they be resurrected? Paul stressed that this resurrection still lay ahead;
it was not something they would experience right after they died. By the time Paul wrote 1 Corinthians, some disciples had already “fallen asleep in death,” for example, the apostle James. (
Acts 12:1, 2) Other apostles and anointed ones would yet fall “asleep in death.”—
1 Cor. 15:6."
For someone to inherit an incorruptible body, that body has to be edited or a new one given to them.
Regarding sin being genetic:
What Was the Original Sin? — Watchtower ONLINE LIBRARY (jw.org)]
Under the heading "A Grasp at Moral Independence"
"By asserting their independence, Adam and Eve irreparably damaged their relationship with Jehovah and
inflicted sin’s imprint upon their organism, right to its genetic foundations. True, they lived for hundreds of years, but they began to die “in the day” of their sin, as a branch severed from a tree would. (
Genesis 5:5) Moreover, for the first time, they sensed an internal disharmony. They felt naked and tried to hide from God. (
Genesis 3:7, 8) They also felt guilt, insecurity, and shame. Their sin produced an upheaval within them, their consciences accusing them of wrongdoing."
"13. What can a person do about (a) the bad tendencies he has ‘picked up’ from his environment? (b) his |inherited tendencies that are bad?
13 Even today a person can genuinely get rid of the things that he has ‘picked up’ from his environment, with the help of God’s Word, His spirit and his own association with God’s servants.
But it is different with the things that come through his genetic makeup, that are a part of him, physically and mentally. True, he can fight these faults with considerable success, for the apostles tell us that we can ‘make our minds over,’ “put on the new personality,” ‘produce the fruits of the spirit,’ “hold a good conscience” and ‘maintain fine conduct.’ (
Romans 12:2; Ephesians 4:24; Galatians 5:22, 23; 1 Peter 3:16; 2:12) But we cannot
completely wipe out these bad inherited tendencies merely through such effort. The apostle said of his situation: “Miserable man that I am! Who will rescue me from the body undergoing this death? Thanks to God through Jesus Christ our Lord! So, then, with my mind I myself am a slave to God’s law, but with my flesh to sin’s law.”—
Romans 7:24, 25.|"
For genetic affects of sin to disappear, the body has to be edited obviously.
Regarding memory:
Why Would God Permit Suffering? — Watchtower ONLINE LIBRARY (jw.org)
"20.
How will the suffering of the past be erased?
20 While the suffering of centuries has been very painful for those who have been victimized by it, it has served a good purpose. It could be compared to permitting your child to have a painful operation to correct a major health problem.
The long-term benefits far outweigh any temporary pain. In addition, the
future that God has purposed for this earth and humans on it will lift the weight of the past from memory: “The former things will not be called to mind, neither will they come up into the heart.” (
Isaiah 65:17) Hence,
whatever suffering that humans have experienced will eventually be erased from the minds of those living when God’s rulership holds sway over all the earth. At that time the joys will crowd out all the previous bad memories, for God “‘will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.’ And the One seated on the throne said: ‘Look! I am making all things new.’”—
Revelation 21:4, 5."
This supports Deejes point regarding those resurrected on earth.
Also:
The End of Sickness and Death — Watchtower ONLINE LIBRARY (jw.org)
"16 As to the resurrected ones, God will accurately
“re-create” each individual with his entire life pattern, personality and memory just as it was. The one resurrected will be able to identify himself as the same person.
Also, his former associates will know him by his appearance and characteristics. He can then resume life after the interruption caused by his death, possessing the same motivations, leanings and traits that he displayed beforehand. However, his past sins and mistakes will not be brought up as charges against him. Why not? Because God’s purpose in bringing him back to earth is to provide opportunity for him to take advantage of Christ’s sacrifice and be freed of sin.
Yet, what the individual did in the past, if bad, would have its effect on his personality, and the resulting bad traits would have to be overcome. The more unrighteous his past course was, the more he will have to change. Some may not take advantage of the opportunity to change.—
Isaiah 26:10."
Repatterning of the personality:
Resurrection — Watchtower ONLINE LIBRARY (jw.org)
"God’s ability to resurrect. For the One with the ability and power to create man in His own image, with a perfect body and with the potential for full expression of the marvelous characteristics implanted in the human personality, it would pose no insurmountable problem to resurrect an individual. If scientific principles established by God can be used by scientists to preserve and later reconstruct a visible and audible scene by means of videotape, how easy it is for the great Universal Sovereign and Creator
to resurrect a person by repatterning the same personality in a newly formed body. Concerning the revitalizing of Sarah to have a child in her old age, the angel said: “Is anything too extraordinary for Jehovah?”—
Ge 18:14; Jer 32:17, 27."
What is also weird, is if sin is inherited, and causes our sinful nature, then how is it that people can change on their own during a thousand years if they just work hard at it? And with the anointed, they undergo instant change, so their sin is immediately taken away isn't it?
Is recreation the same as resurrection?
If the personality is "repatterned" then it is a copy of it and not the same thing. It is like someone copying a picture form memory and drawing it perfectly. It is still a copy, not the original.
I didn't want to overcomplicate this post as there is a lot more from JW.org to unpack.
