at the very end. when this heaven and earth is destroyed.
When jesus comes at the great battle. no angels come with him. He destroyes evil. and sets up his kingdom.
The nations in matt 25 is everyone who ever lived. The nations encompased which he destroyes at armageddon is only people who are alive. Again, the "rest of the dead will not rise for 1000 years.
your making things to dificult for yourself. and this is why you can't see it.
Some biblical examples
Isa 9:7 Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever.
This is one of the Old Testament passages interpreted as referring to the Millennium, allegedly, a literal interpretation of it will lead me to premillennialism.
To me the literal interpretation is this: During Christ's kingdom the increase of peace will have no end.
This is the Premillennial interpretation: The peace will end after a thousand years and the world will see the greatest war ever conceived by human beings.
The premillennial interpretation doesn't sound very literal to me; as a matter of fact, it seems to contradict the literal interpretation to force Revelation 20:1-10 (a passage that does not say anything about the increase of peace, nor does it make any reference to any prophecy in Isaiah whatsoever) into this Isaiah prophecy.
Another example:
Isa 2:4 And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.
Literal interpretation: weapons shall be destroyed forever and there will be no more war EVER.
Premillennial interpretation: Weapons will be destroyed but only for 1000 years, after this they will take the plowshares and their pruninhooks and turn them into swords and spears again, and the nations will lift the sword up against other nations again, and they will learn war again.
the premillennial interpretation seems to contradict the literal interpretation again and raises a lot of questions: the passage in Revelation 20 says that the nations in the four quarters of the earth will go to war and the number of them is like the sand of the sea; this is a lot of people, how long will it take to build an arsenal this big after all the weapons have been destroyed? how long will it take to train all this people to go to war? Who will organize these armies on different nations and make them come as one against Jerusalem? will there be a second Antichrist? Will this be a worldwide rebellion or there still be mortal people loyal to Christ? if so, what's going to happen to them, are they going to just watch with their arms crossed how half of the world rebels against Jesus, or are they going to be killed? If they are killed is there going to be a second "first resurrection" (third for dispensationalists) where the Millennium martyrs are going to rise? And this is just the tip of the iceberg.
