Revelation 21:1-2 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from G-d out of heaven, prepared as a bride adorned for her husband. (KJV)
The "New" heaven and "New" earth The Hebrew-Greek Key Study Bible has the following footnote: "Here we have the description of a new heaven and new earth. The word "new" in Greek is rendered by the word kainos, which means "qualitatively new" and not simply another earth and another heaven. Since our resurrection bodies will be changed, so will the environment in which these new bodies live."
So from the Greek we see that the world will be renewed. Not replaced.
(See also: Isa. 65:17; Isa 66:22; 2 Pet. 3:13)
There is a New Jerusalem, which comes down to earth out of Heaven. It is described starting in verse 9.
Revelation 21:3-8 And I heard a great voice out of heaven saying, Behold, the tabernacle of G-d is with men, and he will dwell with them, and they shall be his people, and G-d himself shall be with them, and be their G-d. And G-d shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful. And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely. He that overcometh shall inherit all things; and I will be his G-d, and he shall be my son. But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death. (KJV)
Here we see the Y'shua is described as the tabernacle. He dwells among us! Y'shua is plainly described as G-d here. He will wipe away our tears. There will be no pain, tears, death or sorrow. WHAT A HAPPY DAY THAT WILL BE!!!!!
He is known as the Alpha and Omega. These are the first and last letters in the Greek alphabet. He is telling us that he always was and always will be.
Y'shua speaks directly to John and commands him to "write".
Y'shua reminds us of his desire to save us. He refers to the "water of life". He spoke to the woman at the well in John chapter 4 of these same "living waters".
His desire is to adopt us and make us his children. The choice however is ours Y'shua is a gentleman and we all have the choice to reject him or accept him.
He reminds us of the consequences of rejecting him in verse 8. Those who reject him will spend eternity in the lake of fire.
Revelation 21:9-27 And there came unto me one of the seven angels which had the seven vials full of the seven last plagues, and talked with me, saying, Come hither, I will shew thee the bride, the Lamb's wife. And he carried me away in the spirit to a great and high mountain, and shewed me that great city, the holy Jerusalem, descending out of heaven from G-d, Having the glory of G-d: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal; And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel: On the east three gates; on the north three gates; on the south three gates; and on the west three gates. And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb. And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof. And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal. And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel. And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass. And the foundations of the wall of the city were garnished with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald; The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst. And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass. And I saw no temple therein: for the L-rd G-d Almighty and the Lamb are the temple of it. And the city had no need of the sun, neither of the moon, to shine in it: for the glory of G-d did lighten it, and the Lamb is the light thereof. And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it. And the gates of it shall not be shut at all by day: for there shall be no night there. And they shall bring the glory and honour of the nations into it. And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb's book of life. (KJV)
In Rev 21:9 Rev 22-5 we have the description of the New Jerusalem.
Bright Crystal clear like jasper
The city has a rectangular base. It measures 1500 miles in length and width.
It's height is also 1500 miles high. Incredible!!! Some believe this is a cube shape while others feel it is a pyramid with the center point of the pyramid being 1500 miles high.
There is a wall around the city. The wall of the city has 12 layers. Each layer is a different precious gem and each has the name of one of the 12 apostles written on it. The wall is 72 yards high. Think about this for a minute. This sounds high at first but when you think about the rest of the city being 1500 miles high it is just a tiny curb around the outside of the city! It think gives us a glimpse at the intricate detail awesome beauty that awaits us there!
There are 3 gates on each side for a total of 12 gates. Each gate has an angel guarding it. The names of the 12 sons of Israel are written on them. Each gate is a single pearl. (Imagine the size of the oyster!!)
The street of the city is pure gold! Imagine walking on a street of Gold! This tells us that G-d is not impressed with earthly wealth. To our earthly minds we know of very little more precious than gold. Yet in the New Jerusalem it will be so commonplace we will be walking on it.
There is not Temple in the City because G-d will be its temple and he shall be with us forever more!!
There will be no need of the Sun and the moon because we will be in the presence of G-d and His brilliance will illuminate the city.
There will never be night and the gates will never close.
There shall be no unclean thing "sin" there and the only ones who will be permitted entrance are those whose names are written in the book of life.
The 21st letter of the Hebrew aleph-beit is the Shin. It means divine
power, provision and protection. Here we see in chapter 21 the eternal provision
of the L-rd. We see him in all His glory and splendor ruling over his creation.
