The center of the kingdom on earth in the millennium will be in Palestine and the earthly government headquarters will be in Jerusalem (labeled above as “The City”). In that day Palestine will be enlarged to its promised dimensions (Num. 14:1-12; Ezek. 47:15-20), and the land will be redistributed to the twelve tribes (Ezek. 48:1-29). Yes, in that day all Israel (all Jews) will live in this new enlarged Palestine and will be prominent in the kingdom. But some who are not Jewish will also live there as welcome strangers (Ezek. 47:22-23). And the land of Palestine will be greatly altered. It will be more level and more fertile; and the cities will all be newly reconstructed (Zech. 14:4, 8, 10; Isa. 35:1-7; 61:4-5).
As I mentioned, Jerusalem will be the government headquarters of the world; and the temple, which will be located just north of the city, is where Christ will sit on His throne—from where He will teach His ways and from where the law will go forth (Isa. 2:2-4).
The city, with the temple, will be much larger than it is now, and it will be protected by the Lord; yet its gates will be open so that all who desire righteousness may enter (Ezek. 48:30-35; Isa. 26:1-4; 35:8-9).
The city, with its government, which will be intermingled or fused with the worship of God and Christ, will be declared holy and set apart for His service; no idols or unclean spirits and anything unclean will be allowed in the city (Ezek. 36:26-27; Zech. 14:20-21). Thus as you can imagine, with such a desire in all hearts to serve the Lord, there will be much joy in the air, with many happy faces, people praising God constantly as they do their work. And all the work that is done in this place of world government will be done with high organization and skill, for every part of it will be directed by the Lord, and all people will have a full knowledge and understanding of His will (Isa. 32:3-4). This great city, with its government will be grand and beautiful, bringing great honor to Christ the King. Listen to its wonderful praise from Isaiah 62:1-12.
Isaiah 62:1-12 For Zion’s sake I will not keep silent, And for Jerusalem’s sake I will not keep quiet, Until her righteousness goes forth like brightness, And her salvation like a torch that is burning. 2 And the nations will see your righteousness, And all kings your glory; And you will be called by a new name, Which the mouth of the Lord will designate. 3 You will also be a crown of beauty in the hand of the Lord, And a royal diadem in the hand of your God. 4 It will no longer be said to you, “Forsaken,” Nor to your land will it any longer be said, “Desolate”; But you will be called, “My delight is in her,” And your land, “Married”; For the Lord delights in you, And to Him your land will be married. 5 For as a young man marries a virgin, So your sons will marry you; And as the bridegroom rejoices over the bride, So your God will rejoice over you. 6 On your walls, O Jerusalem, I have appointed watchmen; All day and all night they will never keep silent. You who remind the Lord, take no rest for yourselves; 7 And give Him no rest until He establishes And makes Jerusalem a praise in the earth. 8 The Lord has sworn by His right hand and by His strong arm, “I will never again give your grain as food for your enemies; Nor will foreigners drink your new wine, for which you have labored.” 9 But those who garner it will eat it, and praise the Lord; And those who gather it will drink it in the courts of My sanctuary. 10 Go through, go through the gates; Clear the way for the people; Build up, build up the highway; Remove the stones, lift up a standard over the peoples. 11 Behold, the Lord has proclaimed to the end of the earth, Say to the daughter of Zion, “Lo, your salvation comes; Behold His reward is with Him, and His recompense before Him.” 12 And they will call them, “The holy people, The redeemed of the Lord”; And you will be called, “Sought out, a city not forsaken.”
