Is earth made new before or after the Millennial Reign? If you BEFORE, then everything I say is pointless to you. That simple.
As pointed out in my post, the Millennial Kingdom is on this present earth. All those that enter into the Kingdom are the survivors of the Tribulation. God's elect from that time period. Both Jew and Gentile. The elect, that have gone onto Glory, are in the Heavenly Mansion.
awelight,
My understanding is that at the time of Christ's return to this world, God's judgment will be levied upon the unsaved along with the destruction of the current heavens and earth, and be replaced with the new heavens and earth. The old will not be healed (so to speak). I therefore do not believe a Millennial Reign is possible. The key to, and confirmation of this can be found by looking at the seventh angel and the seventh (and last) trumpet. When it sounds, Christ will return and in proximity to that, these heavens, earth, and all who remain in them will be destroyed.
Please observe the following:
[1Th 4:16 17 KJV]
16 For the
Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the
trump of God: and the dead in Christ shall rise first:
17 Then we which are alive [and] r
emain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
[1Co 15:52 KJV]
52 In a moment, in the twinkling of an eye, at the
last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
[Luk 21:33 KJV]
33
Heaven and earth shall pass away: but my words shall not pass away.
[Mat 13:39 KJV]
39 The enemy that sowed them is the devil; the
harvest is the end of the world; and the reapers are the angels.
[Mat 24:33-35 KJV]
33 So likewise ye, when ye shall see all these things, know that it is near, [even] at the doors.
34 Verily I say unto you, This generation shall not pass
, till all these things
be fulfilled.
35
Heaven and earth shall pass away, but my words shall not pass away.
[2Pe 3:10 KJV]
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.
[Rev 11:15-19 KJV]
15 And the
seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become [the kingdoms] of our Lord, and of his Christ
; and he shall reign for ever and ever.
16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
17 Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
18 And the nations were angry, and
thy wrath is come, and the time of the dead,
that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
[Rev 10:7 KJV]
7 But in the days of the voice of the
seventh angel, when he shall
begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
[Rev 11:15 KJV]
15 And the
seventh angel sounded; and there were great voices in heaven, saying, The
kingdoms of this world are become [the kingdoms]
of our Lord, and of his Christ; and he shall reign for ever and ever.
[Rev 16:17-19 KJV]
17 And the
seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying,
It is done.
18 And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, [and] so great.
19 And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of
the fierceness of his wrath.
Sinners have been removed from earth and go into Judgement. Jerusalem will be rebuilt out from the destruction of the Tribulation days. Weapons will be turned into plows. Diseases will end. The Lord will bless the earth with proper weather and rains when needed. The Lord will Reign from Jerusalem. Those on the earth shall still be given in marriage and have children. The earth's population will increase rapidly. Death is rare and individuals live for a very long time. Judgement, is swift and permanent under the Lord's rule of Iron. While everyone, going into the Millennial Kingdom were saved individuals - their offspring still suffer from the sin nature. A nature passed on by flesh and blood. There is peace and rest upon the people of Earth. The population of this earth, will consist of both "flesh and blood" and "flesh and bone" In other words, Those still in human bodies and those in glorified bodies. Those in human bodies do not have access to the Heavenly aspect of the Kingdom - yet. Those in glorified bodies (OT, Assembly and Tribulation Martyrs - who have passed into life through the valley of the shadow of death.) move freely from Heaven to earth and back again.
So does this Israel have boundaries in the Millennial Kingdom? Yes. The boundaries promised by God. Is Jerusalem within those boundaries? Yes. I can't define it much better than this.
Respectfully, awelight, I think the reason you had difficulty with defining the boundaries of the nation of Israel is that no earthly Israel will exist after Christ's return. It will be spiritual, not physical in nature.
Eternal Israel is named the Israel of God : spiritual Israel
[Gal 6:15-16 KJV]
15 For
in Christ Jesus neither
circumcision availeth any thing, nor uncircumcision, but a new creature.
16 And as many as walk according to this rule, peace [be] on them, and mercy, and
upon the Israel of God.
[1Pe 1:2 KJV]
2
Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.
[1Pe 2:10 KJV]
10 Which in time past [were]
not a people, but [are] now the people of God: which had not obtained mercy,
but now have obtained mercy.
Why is it that God chose to name the true Israel as the Israel of God and not just Israel? The reason
is that He wanted a distinction between eternal Israel to come with the current earthly Israel
Overall, I think the events as you describe them do not fit the salvation of the Bible. The Bible's salvation has only two two categories of people: those who have been saved and will live eternally, and those who are unsaved and will be destroyed. The same with heaven and earth: the new, eternal; the old, to be destroyed.
So, after positing this, I'm unsure of where we stand? Please feel free to reply.
