{2} And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.

(2) The state of this glorious Church is first described generally to Re 21:3-8, and then specially and by parts, in the verses following. The general description consists in a vision shown afar off, Re 21:2 and in speech spoken from heaven. In the general these things are common, that the Church is holy, new, the workmanship of God, heavenly, most glorious, the spouse of Christ, and partaker of his glory in this verse.

People's New Testament

21:2 And I John saw the holy city, new Jerusalem. The glorified and heavenly Church, pure and beautiful as a bride prepared for the bridegroom. This chapter presents a vision of the final condition of the redeemed and triumphant church. The vision points out the contrast between the beginning and the final condition of our race. The career of man began in a garden, the fitting home of a race few in numbers. It ends, as revealed by the prophet, in a city, the home where multitudes gather. Of this city Jerusalem was a type. The redeemed and holy Church, washed by the Savior's blood, and obedient to his will as a faithful bride to her husband, is the new Jerusalem.

Wesley's Notes

21:2 And I saw the holy city - The new heaven, the new earth, and the new Jerusalem, are closely connected. This city is wholly new, belonging not to this world, not to the millennium, but to eternity. This appears from the series of the vision, the magnificence of the description, and the opposition of this city to the second death, Rev 20:11,12; 21:1,2,5,8,9; 22:5. Coming down - In the very act of descending.

Jamieson-Fausset-Brown Bible Commentary

2. And I John-"John" is omitted in A, B, Vulgate, Syriac, Coptic, and Andreas; also the "I" in the Greek of these authorities is not emphatic. The insertion of "I John" in the Greek would somewhat interfere with the close connection which subsists between "the new heaven and earth," Re 21:1, and the "new Jerusalem" in this verse.

Jerusalem . out of heaven-(Re 3:12; Ga 4:26, "Jerusalem which is above"; Heb 11:10; 12:22; 13:14). The descent of the new Jerusalem out of heaven is plainly distinct from the earthly Jerusalem in which Israel in the flesh shall dwell during the millennium, and follows on the creation of the new heaven and earth. John in his Gospel always writes [Greek] Hierosoluma of the old city; in the Apocalypse always Hierousaleem of the heavenly city (Re 3:12). Hierousaleem is a Hebrew name, the original and holy appellation. Hierosoluma is the common Greek term, used in a political sense. Paul observes the same distinction when refuting Judaism (Ga 4:26; compare Ga 1:17, 18; 2:1; Heb 12:22), though not so in the Epistles to Romans and Corinthians [Bengel].

bride-made up of the blessed citizens of "the holy city." There is no longer merely a Paradise as in Eden (though there is that also, Re 2:7), no longer a mere garden, but now the city of God on earth, costlier, statelier, and more glorious, but at the same time the result of labor and pains such as had not to be expended by man in dressing the primitive garden of Eden. "The lively stones" were severally in time laboriously chiselled into shape, after the pattern of "the Chief corner-stone," to prepare them for the place which they shall everlastingly fill in the heavenly Jerusalem.

Matthew Henry's Concise Commentary

21:1-8 The new heaven and the new earth will not be separate from each other; the earth of the saints, their glorified, bodies, will be heavenly. The old world, with all its troubles and tumults, will have passed away. There will be no sea; this aptly represents freedom from conflicting passions, temptations, troubles, changes, and alarms; from whatever can divide or interrupt the communion of saints. This new Jerusalem is the church of God in its new and perfect state, the church triumphant. Its blessedness came wholly from God, and depends on him. The presence of God with his people in heaven, will not be interrupt as it is on earth, he will dwell with them continually. All effects of former trouble shall be done away. They have often been in tears, by reason of sin, of affliction, of the calamities of the church; but no signs, no remembrance of former sorrows shall remain. Christ makes all things new. If we are willing and desirous that the gracious Redeemer should make all things new in order hearts and nature, he will make all things new in respect of our situation, till he has brought us to enjoy complete happiness. See the certainty of the promise. God gives his titles, Alpha and Omega, the Beginning and the End, as a pledge for the full performance. Sensual and sinful pleasures are muddy and poisoned waters; and the best earthly comforts are like the scanty supplies of a cistern; when idolized, they become broken cisterns, and yield only vexation. But the joys which Christ imparts are like waters springing from a fountain, pure, refreshing, abundant, and eternal. The sanctifying consolations of the Holy Spirit prepare for heavenly happiness; they are streams which flow for us in the wilderness. The fearful durst not meet the difficulties of religion, their slavish fear came from their unbelief; but those who were so dastardly as not to dare to take up the cross of Christ, were yet so desperate as to run into abominable wickedness. The agonies and terrors of the first death will lead to the far greater terrors and agonies of eternal death.
