You have been deceived by the devil's false soothing spirit of hyper-grace found in dispensationalism and replacement theology. The gospel of the kingdom is only proclaimed until it has reached the whole world (including Jerusalem in Judah where it started out from), then the final end of this earth will come:
Matthew 24 (ESV)
14 And this gospel of the kingdom will be proclaimed throughout the whole world as a testimony to all nations, and then the end will come.
29 "Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken.
30 Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory.
There is no earth left after the next return of Jesus Christ / Yeshua ha'Mashiach.
You are talking about the part of Israel that never accepts Christ / Messiah. They are lost forever. That portion of Israel that eternally rejected Jesus Christ / Yeshua ha'Mashiach, their broken covenant was never renewed, their eternal rejection of God's grace will be met with His eternal rejection of them - its a broken covenant they are clinging to, if they do not enter the renewed covenant under Jesus Christ / Yeshua ha'Mashiach before his next final return.
Before Ezekiel 37 - 48 comes into fruition, and the great tribulation of the anti-Christ follows all days on earth, as he enters the renewed Ezekiel 40 temple, as a god to be worshipped only, at the last 3.5 years of the existence of this earth, the Jews' spirit of stupor of Romans 11, will also be lifted with the spirit of grace, and they will also join Romans 11's Olive Tree, the renewed Israel Body of Christ when the prophesy of Zechariah 12:10 goes into fruition:
Romans 11 (ESV)
7 What then? Israel failed to obtain what it was seeking. The elect obtained it, but the rest were hardened,
8 as it is written, "God gave them a
spirit of stupor, eyes that would not see and ears that would not hear, down to this very day."
15 For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead?
Zechariah 12 (ESV)
10 "And I will pour out on the house of David and the inhabitants of Jerusalem a
spirit of grace and pleas for mercy, so that, when they look on me, on him whom they have pierced, they shall mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a firstborn.
When Christ returns for his renewed Israel Body of Christ, he destroys this earth and all on it that are not raptured after the great tribulation. Mathew 24:29
Matthew 24 (ESV)
29 "Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken.
2 Peter 3 (ESV)
10 But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies will be burned up and dissolved, and the earth and the works that are done on it will be exposed.
Revelation 21 (ESV)
1 Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more.
1 Corinthians 3 (ESV)
12 Now if anyone builds on the foundation with gold, silver, precious stones, wood, hay, straw—
13 each one's work will become manifest, for the Day will disclose it, because it will be revealed by fire, and the fire will test what sort of work each one has done.
Luke 17 (ESV)
29 but on the day when Lot went out from Sodom, fire and sulfur rained from heaven and destroyed them all—
30 so will it be on the day when the Son of Man is revealed.
2 Thessalonians 1 (ESV)
7 and to grant relief to you who are afflicted as well as to us, when the Lord Jesus is revealed from heaven with his mighty angels
8 in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus.
Malachi 3 (ESV)
2 But who can endure the day of his coming, and who can stand when he appears? For he is like a refiner's fire and like fullers' soap.
Psalms 50 (ESV)
3 Our God comes; he does not keep silence; before him is a devouring fire, around him a mighty tempest.
Isaiah 66 (ESV)
15 "For behold, the Lord will come in fire, and his chariots like the whirlwind, to render his anger in fury, and his rebuke with flames of fire.
Revelation 20 (ESV)
9 And they marched up over the broad plain of the earth and surrounded the camp of the saints and the beloved city, but fire came down from heaven and consumed them,
10 and the devil who had deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet were, and they will be tormented day and night forever and ever.
