The new Jerusalem is not coming down until the 1000 years are finished and during the 1000 years the earth is void.
Jesus will rule the earth when it is recreated and made new (after the 1000 years), not while it is sinful and desolate or void.
Jer 4:23 explains, “I beheld the earth, and, lo, it was without form, and void; and the heavens … had no light.” Of course, this sounds like it’s right out of Gen 1:2, but if you keep reading: “I beheld the mountains, and, lo, they trembled, and all the hills moved lightly. I beheld, and, lo, there was no man, and all the birds of the heavens were fled” (4:24, 25).
We can easily conclude that since the mountains are now gone, they must have been there before. But if there is any doubt, Jeremiah continues, “I beheld, and, lo, the fruitful place was a wilderness, and all the cities thereof were broken down” (V. 26). Now we have cities that are broken down, so this cannot be at the time of the garden of Eden or a pre-creation picture.
But what breaks it all down? The Bible says “the presence of the LORD, and by his fierce anger.” This chapter also says that there is no life on earth at this time, and moreover, the slain of the Lord covers one end of the earth to the other. Furthermore, “They shall not be lamented, neither gathered, nor buried; they shall be dung upon the ground” (Jer 25:33).
Well, it’s very simple. When Jesus comes down with power, the righteous, both the living and the dead, who are resurrected, are caught up with Him, and the sinful living are destroyed by the brightness of His coming. And as Revelation 20 says, “The rest of the dead lived not again until the thousand years were finished” (v. 5).
