Revelation 3:21 “He who overcomes, I will grant to him to sit down with Me on My throne, as I also overcame and sat down with My Father on His throne.” (NASB95)
Revelation 3:21 “He who overcomes, I will grant to him to sit down with Me on My throne, as I also overcame and sat down with My Father on His throne.” (NASB95) Those believers who survived the Tribulation who remain on the earth and have yet to receive their resurrection bodies will repopulate the earth. Those born will have sin natures and will thus need to get saved through faith alone in Christ alone.
All of creation will be at peace during the Millennium (Zech. 3:9) and there will be no war during the Millennium.
Isaiah 2:1 The word which Isaiah the son of Amoz saw concerning Judah and Jerusalem. 2 Now it will come about that in the last days the mountain of the house of the LORD will be established as the chief of the mountains, and will be raised above the hills; And all the nations will stream to it. 3 And many peoples will come and say, “Come, let us go up to the mountain of the LORD, to the house of the God of Jacob; That He may teach us concerning His ways and that we may walk in His paths.” For the law will go forth from Zion and the word of the LORD from Jerusalem. 4 And He will judge between the nations, and will render decisions for many peoples; And they will hammer their swords into plowshares and their spears into pruning hooks. Nation will not lift up sword against nation, and never again will they learn war. (NASB95) There will be international prosperity. The life of a man being during the millennium will be greatly increased.
Isaiah 65:17 “For behold, I create new heavens and a new earth; And the former things will not be remembered or come to mind. 18 But be glad and rejoice forever in what I create; For behold, I create Jerusalem for rejoicing and her people for gladness. 19 I will also rejoice in Jerusalem and be glad in My people; And there will no longer be heard in her The voice of weeping and the sound of crying. 20 No longer will there be in it an infant who lives but a few days, or an old man who does not live out his days; For the youth will die at the age of one hundred and the one who does not reach the age of one hundred will be thought accursed. 21 They will build houses and inhabit them; They will also plant vineyards and eat their fruit. 22 They will not build and another inhabit, they will not plant and another eat; For as the lifetime of a tree, so will be the days of My people, And My chosen ones will wear out the work of their hands. 23 They will not labor in vain, or bear children for calamity; For they are the offspring of those blessed by the LORD, And their descendants with them. 24 It will also come to pass that before they call, I will answer; and while they are still speaking, I will hear. 25 The wolf and the lamb will graze together, and the lion will eat straw like the ox; and dust will be the serpent's food. They will do no evil or harm in all My holy mountain,” says the LORD. (NASB95) There will be no deserts on the earth (Isa. 35:1-3) and the animal kingdom will be changed (Isa. 11). The original Adamic curse placed upon the creation that is recorded in Genesis 3:17-19 will be removed so that there will be abundant productivity to the earth. The animal kingdom will be at peace as well (Isa. 11:6-9; 35:9; 65:25), all sickness will be removed (Isa. 33:24; Jer. 30:17; Ezek. 34:16) and all deformities will be healed (Isa. 29:17-19; 35:3-6; Jer. 31:8). There will be a supernatural work of preservation of life through the King (Isa. 41:8-14; Jer. 32:27; Ezek. 34:27; Joel 3:16-17; Amos 9:15; Zech. 8:14-15; 14:10-11). There will be freedom from oppression (Isa. 14:3-6; Zech. 9:11-12).
There will be a perfect economic system during the millennium in which the needs of men are abundantly provided for by labor in that system, under the guidance of the King. There will be a fully industrialized society (Isa. 62:8-9; 65:21:23; Jer. 31:5; Ezek. 48:18-19) and agriculture as well as manufacturing will provide employment. There will be economic prosperity because of the perfect labor situation (Isa. 4:1; 35:1-2; 30:23-25; Jer. 31:5; Ezek. 34:26; Mic. 4:1; Zech. 8:11-12; Ezek. 36:29-30; Joel 2:21-27; Amos 9:13-14).
There will be a tremendous increase of solar and lunar light during the millennium (Isa. 4:5; 30:26; 60:19-20). There will be unified worship of the Father and the Messiah (Isa. 45:23; 52:1; Zech. 13:2; 14:16; Zeph. 3:9; Mal. 1:11).
Jerusalem will become the center of the millennial earth (Isaiah 2:2-4; Jeremiah 31:6; Micah 4:1; Zechariah 2:10-11). Because the world is under the dominion of Israel’s King, the center of Palestine becomes the center of the entire earth. Jerusalem will be the center of the kingdom rule (Jeremiah 3:17; 30:16-17; 31:6, 23; Ezekiel 43:5-6; Joel 3:17; Micah 4:7; Zechariah 8:2-3).
The outstanding characterization of the millennium is its spiritual nature. The millennial reign of Christ will be an earthly kingdom but it will be most definitely spiritual in character.
The millennial kingdom will be characterized by righteousness. The key words of the Lord Jesus Christ’s millennial reign are righteousness and peace, the former being the root of which the latter is the fruit.
Isaiah 32:17 And the work of righteousness will be peace, and the service of righteousness, quietness and confidence forever. 18 Then my people will live in a peaceful habitation, and in secure dwellings and in undisturbed resting places. (NASB95) During the millennial reign of the King, the prophecy of Psalm 85:10 will be fulfilled.
Psalm 85:10 Lovingkindness and truth have met together; Righteousness and peace have kissed each other. 11 Truth springs from the earth, and righteousness looks down from heaven. 12 Indeed, the LORD will give what is good, and our land will yield its produce. 13 Righteousness will go before Him and will make His footsteps into a way. (NASB95) The Messiah’s presence in Jerusalem shall be the source from which all millennial righteousness will emanate in spectacular glory.
Isaiah 62:1 “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 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.” (NASB95) Righteousness will be the descriptive term characterizing the rule of the Messiah as a whole. Christ will be the King reigning in righteousness.
