First, we need to unlearn the dogma that we heard growing up and go into the scriptures. This what happens when someone dies:
Ecclesiastes 12
7 Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
So all people who die spirits return back to the father. Spirits never dies, its pure energy. That is heaven in the spiritual world. Your spirit comes back again on Earth as another person.
Ecclesiastes 1
9 The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun.
Ecclesiastes 6
10 That which hath been is named already, and it is known that it is man
Everybody that is on the planet has been here before. Everybody goes through regeneration (which many call reincarnation) from the least to the greatest. Elijah came back as John the Baptist.
Then there is the Kingdom of Heaven which is on earth. That is established after on Judgement Day (the destruction of Babylon the Great which is Amerikkka) and the Battle of Armageddon. The Kingdom of Heaven on earth is for the heirs of the promises: the seed of Jacob (Israel) starting with the Messiah, King David, the 144,000 and the rest of the repented elect of Israel.
Revelation 21
10 And he carried me away in the spirit to a great and high mountain, and shewed me that great city, the holy Jerusalem, descending out of heaven from God,
11 Having the glory of God: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal;
12 And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel
The other nations outside of the descendants of Israel will serve the Israelites primarily the nation of Edom.
Amos 9
11 In that day will I raise up the tabernacle of David that is fallen, and close up the breaches thereof; and I will raise up his ruins, and I will build it as in the days of old:
12 That they may possess the remnant of Edom, and of all the heathen, which are called by my name, saith the Lord that doeth this.
People will gladly bring their sons and daughters to serve the nation of Israel. Yes, slavery will be in full effect on Earth after Judgement Day.
Isaiah 49
22 Thus saith the Lord God, Behold, I will lift up mine hand to the Gentiles (other nations), and set up my standard to the people (Israel): and they shall bring thy sons in their arms, and thy daughters shall be carried upon their shoulders.
23 And kings shall be thy nursing fathers, and their queens thy nursing mothers: they shall bow down to thee with their face toward the earth, and lick up the dust of thy feet; and thou shalt know that I am the Lord: for they shall not be ashamed that wait for me.
Racial harmony?
Nobody will have the courage to fight after the Battle of Armageddon and the brutal slaughter that the 144,000 puts on the enemies of the Most High across the earth. That is when there will be "racial harmony" and everything will be in its proper order with the nation of Israel on top and back in their homeland.
