Humans' everlasting life on earth was God's initial purpose when he created us. His purpose has never changed. Millions of people will be living on the planet transformed into a paradise in the near future (Psal. 37:11,29; Rev. 7:15-17; 21:3,4; Matt. 5:5).
Sounds right.
However, Jehovah and Jesus made an arrangement for a Kingdom from the heavens that was suitable for humans, a group of people who were chosen to live there after having experienced humanity in their own flesh, and thus be able to rule from there.
I don't know what you mean by a Kingdom from the heavens. But I do know that there is one Kingdom of God and it will include the Kingdoms of the earth.
Rev 11:15
Then the seventh angel sounded his trumpet, and loud voices called out in heaven: “The kingdom of the world has become the kingdom of our Lord and of His Christ, and He will reign forever and ever.”
You are thinking of Kingdom as meaning Government, but it means the realm over which a King rules. If the King rules over the earth then the earth is part of the Kingdom.
Even the OT saints are in the Kingdom of God.
Luke 13:28,29 “You will see Abraham, Isaac, Jacob, and all the prophets in God’s kingdom. But you will be left outside. There you will cry and grind your teeth with pain. People will come from the east, west, north, and south. They will sit down at the table in God’s kingdom.
The New Jerusalem will come down out of heaven and the nations will bring stuff into the city and God will be there to dwell with His people and Jesus and all those who will be with Him forever will also be there,,,,,,,,,,,,,,,,,,,,,,,, on the earth, in the New Jerusalem.
Rev 21:1 Then I saw “a new heaven and a new earth,”[
a] for the first heaven and the first earth had passed away, and there was no longer any sea. 2 I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. 3 And I heard a loud voice from the throne saying, “Look! God’s dwelling place is now among the people, and he will dwell with them. They will be his people, and God himself will be with them and be their God.
Rev 21:9 One of the seven angels who had the seven bowls full of the seven last plagues came and said to me, “Come, I will show you the bride, the wife of the Lamb.” 10 And he carried me away in the Spirit to a mountain great and high, and showed me the Holy City, Jerusalem, coming down out of heaven from God.
Rev 21:22 I did not see a temple in the city, because the Lord God Almighty and the Lamb are its temple. 23 The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp. 24 The nations will walk by its light, and the kings of the earth will bring their splendor into it. 25 On no day will its gates ever be shut, for there will be no night there. 26 The glory and honor of the nations will be brought into it. 27 Nothing impure will ever enter it, nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb’s book of life.
Where do you get the idea that Jesus and 144000 anointed Christians who are spirits will stay in heaven?
Don't tell me, I know where. So why do you believe it when the Bible clearly contradicts it?
Those "who have been bought from the earth" (Rev. 14:3), the "firstfruits to God and to the Lamb" (Rev. 14:4), "the congregation of the firstborn who have been enrolled in the heavens" (Heb. 12:23) will NEVER AGAIN dwell on earth as human of flesh and bones:
All Christians have been redeemed by Jesus, they have been bought with the blood of Christ and have His Spirit in them.
All Christians are the firstfruits to God and to the Lamb and are blameless because Jesus is our righteousness. (Jer 23:6, 33:16)
All Christians have been enrolled in the heavens. That does not mean they live there, it means that they are in the Lambs book of life in heaven.
Heb 12:22 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, 23 and to the assembly of the firstborn who are
ienrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, 24 and to Jesus, the mediator of a new covenant, and to
lthe sprinkled blood that speaks a better word than the blood of Abel.
And there are spirits of righteous people made perfect in heaven now and were there when Hebrews was written. They will be brought back to earth by Jesus when He returns, so that they can be resurrected.
1Thess 4:14 For
isince we believe that Jesus died and rose again, even so,
through Jesus, God will bring with him those who have fallen asleep. 15 For this we declare to you by a word from the Lord, that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep. 16 For
nthe Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. 17 Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord. 18 Therefore encourage one another with these words.
1 Thess. 4:17 Afterward we the living who are surviving will, together with them, be caught away in clouds to meet the Lord in the air; and thus we will always be with the Lord.
Being always with the Lord does not mean staying in the air, it means being in the New Jerusalem (for a start) and with immortal bodies we can be in heaven also or anywhere else.
John 14:2 In the house of my Father are many dwelling places. Otherwise, I would have told you, for I am going my way to prepare a place for you. 3 Also, if I go my way and prepare a place for you, I will come again and will receive you home to myself, so that where I am you also may be.
... 17:24 Father, I want those whom you have given me to be with me where I am, in order that they may look upon my glory that you have given me, because you loved me before the founding of the world.
Does not mean that they will be in heaven and never on earth.
Phil. 3:20 But our citizenship exists in the heavens, and we are eagerly waiting for a savior from there, the Lord Jesus Christ,
Jesus Kingdom is not of this world, it is a heavenly Kingdom because that is where it authority comes from. It is not something men have set up, it is something God has set up. We are citizens of that Kingdom and it spreads to the earth and everywhere.
Heb. 12:14 Pursue peace with all people and the sanctification without which no man will see the Lord. (...) 22 But you have approached a Mount Zion and a city of the living God, heavenly Jerusalem, and myriads of angels 23 in general assembly, and the congregation of the firstborn who have been enrolled in the heavens, and God the Judge of all, and the spiritual lives of righteous ones who have been made perfect, 24 and Jesus the mediator of a new covenant, and the sprinkled blood, which speaks in a better way than Abel’s blood.
That would have to be a quote from the New World Translation.
All other translations have "and the spirits of the righteous made perfect". But JWs do not believe we have a spirit that is any more than a life force and so they have to say "the
spiritual lives of righteous". That looks like a dishonest translation to me.
in joyful assembly, to the congregation of the firstborn, enrolled in heaven. You have come to God the Judge of all, to the spirits of the righteous made perfect,

Eph. 2:19 So you are no longer strangers and foreigners, but you are fellow citizens of the holy ones and are members of the household of God
Does that mean that the 144000 live in heaven forever? I can't see it.
Basically I don't see the scriptural arguments for your position but do see good arguments against it.
It looks to me like JWs have been told that certain scriptures mean certain things and even though they don't mean those things, they are in the group now and have to go along with and obey the Governing Body and not rock the boat, or they suffer the consequences.
