The fire, as described by 2 Peter 3 and in 70 + other Prophesies, will happen BEFORE Jesus Returns, to reign for the next thousand years. Psalms 11:4-6, Habakkuk 3:4
No, that is not possible because 2 Peter 3:10-12 clearly describes the burning up of the entire earth (it even says "everything will be destroyed".
2 Peter 3:10 But the day of the Lord will come like a thief.
The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare. 11 Since
everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives 12 as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat. 13 But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells.
Your doctrine contradicts this passage.
Another thing to point out is that what is described here will happen "in keeping with his promise". Which promise? The promise of His return that the scoffers scoff at in the last days (2 Peter 3:3-4).
How anybody can think that we are in the Millennium now, is incredible.
It's incredible to me that anyone can think otherwise when you consider what scripture actually teaches about when Christ reigns and how many resurrection events and judgment days there will be (just one).
Is the world like Isaiah 2:1-6?
Why are you interpreting Isaiah 2:1-6 in such a wooden literal way? That passage is undeniably a reference to "the last days".
Isaiah 2:1 This is what Isaiah son of Amoz saw concerning Judah and Jerusalem: 2
In the last days the mountain of the Lord’s temple will be established as the highest of the mountains; it will be exalted above the hills, and all nations will stream to it.....
Do you somehow not know that the last days had already started by the time the day of Pentecost and the first pouring out of the Holy Spirit occurred long ago?
Acts 2:
14 Then Peter stood up with the Eleven, raised his voice and addressed the crowd: “Fellow Jews and all of you who live in Jerusalem, let me explain this to you; listen carefully to what I say. 15 These people are not drunk, as you suppose. It’s only nine in the morning! 16
No, this is what was spoken by the prophet Joel: 17 “‘In the last days, God says, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams.
So, the last days began long ago already and, according to Peter, they lead up to the return of Christ because he indicated that in the last days there would be scoffers scoffing at the promise of His return.
2 Peter 3:3 Above all, you must understand that
in the last days scoffers will come, scoffing and following their own evil desires. 4 They will say, “Where is this ‘coming’ he promised? Ever since our ancestors died, everything goes on as it has since the beginning of creation.”
So, are you interpreting Isaiah 2:1-6 while keeping in mind that the last days basically cover the time period from the first to the second coming of Christ? It doesn't appear that you are.
