My brothers and sisters in Jesus Christ,
The last enemy that shall be destroyed is death. 1 Corinthians 15:26
During the 1,000 year reign of Christ (1 Corinthians 15:25) there will be people (Babylonians - Daniel 7:4 (Daniel 2:37,38), Medes and Persians - Daniel 7:5 (Daniel 2:39a, 8:3,4,20, 11:2a), and the Greeks and the rest of humanity - Daniel 7:6 (Daniel 2:39b, 8:5,8,21,22, 11:3,4) - because of Daniel 7:12) dying and going to hell, that do not believe in Jesus. And there will be people (John 6:44,65, Matthew 7:17a,18a, 13:37, Luke 6:43a, Romans 9:23,24) dying and going to heaven, that do believe in him. At the (just before the) return of Jesus, only the lowest "heaven" (Revelation 6:13) (singular), above us, rolls up like "a scroll" (Revelation 6:14) - and "the stars" (Daniel 8:10, Matthew 24:29, Mark 13:25, Revelation 6:13) in that heaven fall. At the end of the 1,000 year reign of Jesus, all of "the heavens" (Isaiah 34:4) (plural), above that, roll up "together as a scroll" (Isaiah 34:4) - and all of the stars in those heavens will fall - on the last day of the 1,000 year reign of Jesus. On that day, still during the last day because, "one day is with the Lord as a thousand years, and a thousand years as one day" (2 Peter 3:8), and it is still during that day, being the last day of that 1,000 year reign - is when the "fervent heat" (2 Peter 3:10,12) will happen, and "the heavens being on fire shall be dissolved" (2 Peter 3:12) (2 Peter 3:7,11a) (Revelation 16:17-21) - right after the judgment (Matthew 25:31-46, Revelation 20:11-15) takes place, as "heaven and earth" (Matthew 5:18, 24:35, Mark 13:31, Luke 16:17, 21:33) pass away, "the law" (Matthew 5:18) passes away - and along with it "death" (Hosea 13:14, 1 Corinthians 15:54,55), as we all "put on immortality" (1 Corinthians 15:53,54), because:
The sting of death is sin; and the strength of sin is the law. But thanks be to God, which giveth us the victory through our Lord Jesus Christ. 1 Corinthians 15:56,57
- and enter into "the world to come" (Matthew 12:32, Mark 10:30, Luke 18:30, Hebrews 2:5, 6:5) (Isaiah 65:17, 66:22, Luke 20:35, Ephesians 1:21, Revelation 21:1) (as the world was created by God "without end" (Isaiah 45:17, Ephesians 3:21), but just transformed - as the first world ended in water (2 Peter 2:5, 2 Peter 3:6), and this current world we are now in will end in fire (2 Peter 3:7,10-12) - as that is what the word "worlds" (Hebrews 1:2, 11:3) (plural) means in the word of God. It does not mean other worlds, as in huge planets, because planets are stars (the word planets comes from the Greek "planetes asteres", meaning "wandering stars"), the size of figs (Judges 5:20, Job 38:7, Isaiah 34:4, Daniel 8:10, Revelation 1:16,20, 2:1, 6:13, 9:1, 12:1).
The word corruption means that a body rots after death (Acts 2:31). The word immortal means to never die.
Everyone who rises at "the first resurrection" (Revelation 20:5,6), "the resurrection of the just" (Luke 14:14) (Luke 20:35,36, John 5:29a), the day Jesus returns, will be "raised incorruptible, and we shall be changed" (1 Corinthians 15:52) - into "incorruptible" (1 Corinthians 15:52) bodies, also not able to see rot after death, as death will still be in the world during the 1,000 year reign of Christ.
The word of God says:
And as it is appointed unto men once to die, but after this the judgment: Hebrews 9:27
and
For the Father judgeth no man, but hath committed all judgment unto the Son:" John 5:22
So just as Jesus (John 11:25) judged that men should rise from death (John 11:43,44, Mark 5:41,42, Luke 7:14,15, 8:54,55, Matthew 10:8, 27:52,53), that later died (and die) again, everyone who rises at the first resurrection (1 Corinthians 15:52) will be able to die again during the 1,000 year reign of Christ, except for those about whom it is written (Revelation 20:4-6) - all, having "put on incorruption" (1 Corinthians 15:53,54) during that time (all of those in Christ). Later, after the 1,000 year reign of Christ, having "put on immortality" (1 Corinthians 15:54) the moment "the law" (Matthew 5:18) passes away, we will be like "the angels" (Matthew 22:30, Mark 12:25, Luke 20:36), with physical bodies (Genesis 19:1-10,16) - and that will be the argument of the Devil, when he is released from "his prison" (Revelation 20:7), near the end of the thousand year reign of Jesus (for a "season" (Daniel 7:12, Revelation 20:3)). He will say, "Look at how the earth only changed a little - a mere earthquake, that caused the mount of Olives to be cleft in half and dissapear (Zechariah 14:4), along with the small amount of land that became a plain (Zechariah 14:10). Look at how everything was not burned up like the Bible said it would be (2 Peter 3:7,10-12 - and everything in your post T7t7). Look at how all of the mountains are still in the world, and the sea is still here, when the word of God said they would be gone (Revelation 16:20, 21:1). And eternal life is a lie. Look at how people are still dying until this day. And Jesus, look at how he hid from the people (John 8:59). He even said, put your finger on my hands and put your hand into my side (John 20:27), as he is not a ghost (Luke 24:39) - after he claimed to have risen from the dead. So we can win people. We can defeat Jesus and win." That is the lie Satan will convince the people with, and fool the whole world (Ezekiel chapter 38) to surround "the camp of the saints about, and the beloved city" (Revelation 20:9) (Ezekiel 48:30-35) - when "fire" (Revelation 20:9) comes down and destroys them all on the last day of the 1,000 year reign of Jesus.
Glory to God.
