No, the heavens and the earth would be changed, as Hebrews 1:12 tells us. "And as a vesture shalt thou fold them up, and they shall be changed..." This was not to annihilate the planet or the heavens, but to change the conditions in them so as to make their environment entirely new by the process. This has literally happened already back in the AD 70 period. The conditions in the heavens and the earth today are not what they were before that point.
What did Jesus say? It would be burnt up, melt with fervent heat, along with the "works of the earth", which I believe to be the sin that corrupts the creation.
Isaiah 65's description of the NHNE environment mentions the presence of sinners in it (Is. 65:20), so this NHNE cannot be referring to the eternal state at the culmination of fallen mankind's history on this planet (when the presence of all remaining human evil will be gone). When 2 Peter 3:10 wrote about the "works therein shall be burnt up", he was referring to the physical works of men's hands being burned up (like the 2nd temple) - not a destruction of all sin or the sin nature being burned up.
You need to be the word sin, before saying anything about Isaiah 65:20. I know, it is so much easier not to actually "read" the passage to understand how words are being used. The word sin here is not sin as in evil, but is sin as in missing the mark. The mark here is living to be over 100 years. (Sin is an archery term, that means to miss the mark or standard.) The one who fails to reach 100 years will be lightly esteemed. This is all saying that those living in the new earth will live a long time. However, I believe most believe that everyone will be immortal. That would give some context to what is being said here. There will be no one living less than 100 years.
Hebrews 12:27 also refers to this shaking process for the heavens and the earth that would "remove" those "things that are made", so that the unshaken spiritual realities of the NHNE under the conditions of the New Covenant would remain. You are trying to make the NHNE the period on the end of a sentence, when it was the semi-colon instead.
"25 See to it that you do not refuse Him who is speaking. For if those did not escape when they refused him who warned
them on earth, [
i]much less
will we
escape who turn away from Him who
warns from heaven. 26 And His voice shook the earth then, but now He has promised, saying, “Yet once more I will shake not only the earth, but also the heaven.” 27 This
expression, “Yet once more,” denotes the removing of those things which can be shaken, as of created things, so that those things which cannot be shaken may remain. 28 Therefore, since we receive a kingdom which cannot be shaken, let us [
j]show gratitude, by which we may offer to God an acceptable service with reverence and awe; 29 for our God is a consuming fire."
What remains? Not creation. The Kingdom remains. "Therefore, since we receive a
kingdom which cannot be shaken..."
What do you think happened when God physically got rid of the high priesthood system and the physical temple which it served? These were physical, literal realities that were shaken and removed during the AD 66-70 period. Christ alone was left unchallenged as the Great High Priest without any rival elements of the Levitical high priesthood functioning anymore. He is the only power and authority as the "Head of all things to the church". That is power, and that is authority.
I think you a reading way too much into things simply because of your beliefs, and not because there is any actual scriptural backing.
I have certainly done a study on demonology, and found that God got rid of them all by the close of AD 70. Satan is NOT still here, and neither are his devils and the unclean spirits either.
I highly recommend you look into Gary Bates, and his studies on aliens. He does a very good job of proving it to be demons. UFOs and such, have been bound to the occult since before Walter Martin, who did a lot of study in the area. His cameraman captured an accepted photo of a UFO. To them it wasn't a question of whether they exist, but what are they.
Those gnashing their teeth and weeping was the judgment of the living unbelievers trapped in Jerusalem who saw the resurrected saints joining Christ as He left the Mount of Olives to return to heaven with all of them back in AD 70.
Again, nope. That is the reaction of the "children of the kingdom" who rejected their Messiah, and are as such, locked outside the gates of the eternal kingdom. They were right there, had it all, and now its lost. It will be such agony that it is pictured as wailing and gnashing of teeth. A good anime can show you what that looks like.
As long as you remain in the Pre-mil camp, you will believe this. But it all runs contrary to the way scripture speaks about the Antichrist / antichrists and the other Beast characters. Antichrists are never equated with being the Beast. This is a teaching that is force-fed into the passages. Scripture never says the entire world will worship the Antichrist / Man of Lawlessness - only that he will "exalt himself" over those who were being called god and given homage as if they were God. These antichrists were fellow Zealot leaders who also, just like the Man of Lawlessness, wanted to claim the Messiah the Prince role as the savior of Israel. The Man of Lawlessness exalted himself over all of these other antichrist pretenders, and was able to get into the 2nd temple and present himself as the King of the Jews in that location. Ancient history.
You run contrary to scripture when you speak of the Antichrist (which the Bible presents as a singular apex person surrounded by antichrists), demons, Satan, etc. The Antichrist is the beast. It is as forced on scripture as the trinity. And it does say that the whole world will worship. Revelation is very clear on this fact. This is why Babylon is destroyed. The antichrist is as close to incarnation as Satan will ever get, and he will not suffer worship of anyone but himself. He even called for Jesus, God Himself, to worship him. Did you know that, save for the fire that destroyed the temple, Vesperian ALMOST caused another abomination of desolation event? He had already planned it out. He was only stopped because you kind of need a temple to be able to do that. It was never his plan to destroy the temple.
