I think the stabilizing factor will be that the “Word of God” will rule the nations with a “
rod of iron” after smiting those nations. (Revelation 19:15) I think your are confusing the nations with the chosen people of God, who will live in the land given to Jacob (Ezekiel 37:15-28).
New American Standard Bible (Revelation 19:15)
From His mouth comes a sharp sword, so that with it He may strike down the nations, and He will rule them with a
rod of iron; and He treads the wine press of the fierce wrath of God, the Almighty.
No -I was speaking of those who are made immortal -not those who live on as humans to repopulate the earth after the great tribulation spoken of by Christ (essentially WWIII) and the day of the Lord.
Those made immortal will "inherit the Earth" by reigning with Christ on Earth as kings and priests for the thousand years which follow his return.
Those humans of all nations who live on into the thousand years will all go up to Jerusalem to keep the feast of tabernacles each year -or they will receive no rain.
Christ will indeed rule with a rod of iron, but will essentially be enforcing peace as the law goes forth from Jerusalem and the nature of life on Eaeth is changed.
All of the tribes of Israel who live on as humans will be reunited (Israel had split into the two houses of Judah and Israel) and dwell in the holy land.
There will be only one more attempt at war after the thousand years -which will be put down.
As of the increase of his government and peace there will be no end, humans will continue to reproduce on Earth -eventually being made immortal -and the "children of God" will inherit the entire creation -including the heavens which were "formed to be inhabited" -and will not remain only on Earth.
50Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
51Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
52In 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.
53For this corruptible must put on incorruption, and this mortal
must put on immortality.
54So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
Zech 14:16And 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.
17And it shall be,
thatwhoso 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.
18And if the family of Egypt go not up, and come not, that
have no
rain; there shall be the plague, wherewith the LORD will smite the heathen that come not up to keep the feast of tabernacles.
19This shall be the punishment of Egypt, and the punishment of all nations that come not up to keep the feast of tabernacles.
Phil 3:21Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
Romans 8:18I consider that our present sufferings are not worth comparing with the glory that will be revealed in us.
19For the creation waits in eager expectation for the children of God to be revealed. 20For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope
21that
h the creation itself will be liberated from its bondage to decay and brought into the freedom and glory of the children of God.
22We know that
the whole creation has been groaning as in the pains of childbirth right up to the present time.
23Not only so, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for our adoption to sonship, the redemption of our bodies.
24For in this hope we were saved. But hope that is seen is no hope at all. Who hopes for what they already have?
25But if we hope for what we do not yet have, we wait for it patiently.
