You can make those false assumptions all you want but it won't change the actual Scripture evidence I showed you from 2 Peter 3. Now you were the one who quoted 2 Peter 3:10 about the "day of the Lord", I didn't. And that's what was laughable to me, because that "day of the Lord" is the last day of this world when Jesus comes, and is also the start of His future "thousand years" reign of Revelation 20.
The problem you speak of is with those men who have deceived you, because they... obviously don't understand how the Revelation 20 chapter is literal.
And one of their fake ploys, which reveals their Biblical ignorance by the way, is how they immediately bring up a false matter that the Book of Revelation of so symbolic, that many mistake symbology in it for being literal! That's funny, since NOT EVERYTHING written in Christ's Book of Revelation is symbolic! To say so is to make out our Lord Jesus Christ as a fool! And that's exactly what those men behind that false Amillennial theory are about, out to make Jesus look like a fool.
So why side with those men, and why not instead listen to Jesus Christ in His Word of Truth?
And thus you reveal the problem of Bible interpretation those same men you listen to have, they mistake Bible prophecy that is mixed within history. Did you not notice God mentioning that Isaiah 13 Scripture of the time when He would destroy Babylon through the Medes of history?
Isa 13:17-20
17 Behold, I will stir up the Medes against them, which shall not regard silver; and as for gold, they shall not delight in it.
18 Their bows also shall dash the young men to pieces; and they shall have no pity on the fruit of the womb; their eye shall not spare children.
19 And Babylon, the glory of kingdoms, the beauty of the Chaldees' excellency, shall be as when God overthrew Sodom and Gomorrah.
20 It shall never be inhabited, neither shall it be dwelt in from generation to generation: neither shall the Arabian pitch tent there; neither shall the shepherds make their fold there.
KJV
It's obvious those you heed don't understand prophetic speech, nor what God showed through Solomon that there is no new thing under the sun, what has been shall be again. The "day of the Lord" part is also covering the very end of this present world too, but back in history with the literal destruction of Babylon, God used that "day of the Lord" language to also point to Babylon's destruction back then by the Medes, and thus geographical Babylon still lay barren in the desert and mostly uninhabited. Saddam Husein tried to rebuild it. Therefore, Jesus uses Babylon as an object to be destroyed also in His Book of Revelation for the end of this world. So you tell me, who is really given to understand which parts of Revelation are symbolic, and which parts are literal? Definitely not those men you follow.
Now if you have to have absolute proof of Christ's future reign over the wicked after His future return, that is easy; it's right here...
Immediately after the battle on the "day of the Lord", when Jesus ONLY is king over all the earth and is reigning...
Zech 14:7-9
7 But it shall be one day which shall be known to the LORD, not day, nor night: but it shall come to pass, that at evening time it shall be light.
8 And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be.
9 And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one.
KJV
Those left of the nations that came up against Jerusalem on the last day, after that battle on the "day of the Lord" (i.e., Armageddon), are still present in that time of Christ's future reign...
Zech 14:16-17
16 And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.
17 And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.
KJV
