The earth being cleansed, and all things made new, it will have been prepared for the "dwelling" of "righteous persons" (2 Pet. 3:13), who,--having "put on incorruption" (1 Cor. 15:53), and been "caught up ... in the clouds to meet the Lord in the air" (1 Thess. 4:17), where, constituting "the bride," "the Lamb's wife," they were "called unto the marriage supper of the Lamb" (19:7-9),--will descend from heaven to take possession. Thus John writes, that one of the angels said to him: "Come hither, I will show thee the bride, the Lamb's wife. And he carried me away in the spirit to a great and high mountain, and he showed me that great city, the holy Jerusalem, descending out of heaven from God," 21:9, 10.
"Lo, what a glorious sight appears To our believing eyes: The earth and seas are passed away, And the old rolling skies!
From the third heaven where God resides, That holy, happy place, The New Jerusalem comes down Adorned with shining grace.
Attending angels shout for joy, And the bright armies sing, Mortals, behold the sacred seat Of your descending King."--_Watts._
The Kingdom given to the Saints at the resurrection of the just.
"And I saw thrones, and they sat on them, and judgment was given for them: and I saw the persons of those beheaded for the testimony of Jesus, and for the word of God, and those, who had not worshipped the wild beast, nor his image, nor had received the mark on their forehead, or on their hand; and they lived and reigned with Christ the thousand years. But the rest of the dead lived not until the thousand years were completed. This is the first resurrection. Happy and holy is he, who bath part in the first resurrection: on such, the second death hath no power, but they will be priests of God and of Christ, and will reign with him a thousand years!" Rev. 20:4-6.
"Thrones" are symbols of power. As the saints are to reign with Christ on the renewed earth, in obedience to the invitation: "Come ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world," (Matt. 25:34); their being inducted into the kingdom is symbolized by their being seated on thrones. Thus they sing in the "new song," addressed to Christ: "Thou wast slain, and hast redeemed us to God by thy blood, out of every kindred, and tongue, and people, and nation, and hast made us unto our God kings and priests: and we shall reign on the earth," 5:9, 10. In the first chapter, also, all who ascribe praises to "Him that loved us, and washed us from our sins in his own blood," also add: "and hath made us kings and priests unto God, and his Father," 1:5, 6.
