If this is true, which I will try and show as the thread progresses, assuming that it does, the conclusion will be that it occurs at the beginning of the millennium, IOW both are one and the same. The premil view is still the correct view, only IMO of course. But unfortunately many premils seem to error when they conclude the new heavens and new earth follow the millennium. So, then of course, I will be coming from a premil perspective.
The first thing that has to be determined is the timing of the day of the Lord and if there are more than one, one at the beginning of the millenium, one at the end.
The day of the Lord according to the NT.
1 Thessalonians 5:2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
2 Peter 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
2 Peter 3:12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Let's first go to 1 Thessalonians 5:2. It speaks about it as occuring as a thief in the night. This is further verified in Revelation ch 16.
Revelation 16:15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
This is stated between the 6th and 7th vial. This tells us that the Lord has not yet physically returned at this point. So far then, we can conclude the day of the Lord occurs when Christ returns.
So now let's look at 2 Peter 3...Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Notice the part...wherein dwelleth righteousness. This is being associated with the new heavens and a new earth. So then, when Christ physically returns, will there or will there not dwell righteousness in the earth? If the answer is the former, then one must conclude that the new new heavens and a new earth occur when the millenium begins, Keep in mind everyone, I'm coming from a premil perspective. I fully realize amils, etc are going to agree but disagree. By that I mean, they too believe the new heavens and a new earth begin upon Christ's return. The only difference, the millenium would now be past, not just beginning.
If the premil agrees that righteousness will dwell in the earth upon Christ's return, they then have to agree that the new heavens and a new earth would be the millennium, since 2 Peter 3:13 clearly links the new heavens and a new earth with the dwelling of righteousness in the earth. You can't have one without the other..that's the point. Nowhere in 2 Peter 3 does it imply that when Christ returns there will dwell righteousness, except it won't be the new heavens and new earth just yet. Why wouldn't it be? Surely righteousness doesn't dwell in this earth presently, does it? Surely righteousness will dwell in the earth once Christ returns, right? It's a no brainer then, or at least it seems that way to me. The new heavens and a new earth must occur when Christ returns, and not some 1000 years and a little season later.
I've got a lot more to add, depending on whether this thread elicits discussion. But I'll stop here for now. But I will say this. Revelation ch 20 is very brief about this 1000 years. It is then only logical that ch 21 and 22 are homing in on some of the details surrounding this 1000 years. Not to mention, plenty of places in the OT that can't be speaking of anything but this same period of time. For example, some of Isaiah 65 parallels Revelation 21 and 22. But we'll get to that later, depending on how this thread goes.
So basically I tend to believe that when Christ returns, this begins the new heavens and a new earth. After a period of time satan will be loosed. Then eventually the great white throne judgment. So why might the great white throne judgment occur after the new heavens and a new earth? Perhaps to show that some are not worthy of it, or that they don't want any part of it after experiencing it for the past 1000 years. Perhaps similar to what satan did. he experienced God first hand. Dwelled right that among Him. Yet he still rebelled. It looks like man will do the same thing if the premil view is correct. Keep in mind, man indeed rebelled in the beginning, so to speak. But satan was clearly the one to blame for that. And ironically, satan will be the cause yet again, since it is he that will deceive them to go up against the new Jerusalem. But there is another perspective to ponder. In order for satan to so easily deceive them, rebellion must have been in their hearts all along. That part they can't blame on satan, since he was locked away at the time, IOW during the 1000 years. Keep in mind, a lot of what I said here at the end, it's based upon my opinion and probably isn't something I could easily prove with Scriptures. Just think of it as something that is deduced.
