Revelation chapter 21
Revelation 21:1 - 4 And I saw a new heaven and a new earth: for the first heaven and the first earth are passed away; and the sea is no more. And I saw the holy city, New Jerusalem, coming down out of heaven from God, made ready as a bride adorned for her husband. And I heard a great voice out of the throne saying, Behold, the tabernacle of God is with men, and he shall dwell with them, and they shall be his people, and God himself shall be with them, and be their God: and he shall wipe away every tear from their eyes; and death shall be no more; neither shall there be mourning, nor crying nor pain, any more: the first things are passed away.
Isaiah chapter 54 vs. 12 ‘Oh afflicted city, unconsoled. I will lay your stones in the finest way. Your foundation stones of saphire, Your windows will beam with rubies’.
The Book of Revelation gives some new information about the ‘New Jerusalem City’ which is the glorious eternal home and concerns itself mostly with this city. The rest of the Old Testament is mostly concerned with the ‘Millennial kingdom’ the thousand year reign of the Messiah that comes before the New Jerusalem abode.
This is our glorious eternal home, the New Jerusalem, made of transparent gold. It is being viewed by John, who was taken to a high mountain to see it coming out of heaven. The city exists somewhere today. It has the appearance of a diamond and is also a cube. It has a height of 1200 miles, by the same width and depth. Possibly it looks like the longest skyscraper you ever saw! It has twelve pearly gates named after the twelve sons of Jacob, showing that the Jewish names will go on forever, however there is no mention of any functional difference between Jewish and other people. The city has twelve foundation stones, composed of precious stones. They are named after the twelve apostles.
