21:2 I John. This is the first time that John has identified himself by name since the very beginning (Revelation 1:1, 4, 9) of his message. The scene before his eyes was so magnificent that he must emphasize that he himself was really there observing it.

21:2 new Jerusalem. “The holy city, new Jerusalem,” is the place that Christ has been preparing for His own ever since He returned there after His resurrection (John 14:2-3). It is that city “which hath foundations, whose builder and maker is God” (Hebrews 11:10), that “Jerusalem which is above…the mother of us all” (Galatians 4:26). See also Hebrews 11:16; 12:22-23; 13:14). It will probably be set high in the atmosphere when the Lord brings it with Him at His descent to the air to meet His resurrected and raptured saints (I Thessalonians 4:16-17), and may well remain there as a great satellite orbiting the earth during the tribulation and millennial periods.

21:2 out of heaven. The new Jerusalem is not synonymous with heaven, as many think, for it will come “down from God out of heaven,” and then be established on the new earth, there to remain forever.

21:2 prepared. “Prepared” is the same Greek word as in John 14:2 (“I go to prepare a place for you”), in Hebrews 11:16 (“He hath prepared for them a city”), and in I Corinthians 2:9, “…the things which God hath prepared for them that love Him.”

21:2 bride. The gloriously white city reminds John of a bride coming to her husband, and is even called “the bride, the Lamb’s wife” (Revelation 21:9; see also Revelation 19:7-9; 22:17; Ephesians 5:25-27).
