What does Revelation 21 mean?

Revelation 21

Revelation 21: 1.2And I saw a new heaven and a new earth; for the first heaven and the first earth have passed away, and the sea is no more. And I saw the holy city, new Jerusalem, coming down from God out of heaven, prepared like a bride adorned for her husband.
  In this vision John sees a new earth and a new heaven. Even the sea in its present form will no longer exist. Everything is made new. However, this passage does not mean that there will be no more sea on the new earth. It just says that everything will be made from scratch, including the sea. But we can assume that the sea on the new earth will be completely different. It's going to be so fantastic that we can't even imagine it today.

Note: Today the sea covers about two thirds of the earth's surface. This is certainly the result of the flood (cf. Genesis 7), during which the whole earth was under water for about 5 months. On the new earth, the situation will certainly be different, since there will be no more curse of sin to be seen.

Note: Anyone who trusts the theory of evolution (cf. Evolution vs. Creation) will of course have great difficulties understanding this text. If our earth was created in millions of years, how long will it take for the new earth? One can understand this text only in the belief in a seven-day creation and in a Creator to whom everything is possible (cf. Jesus as Creator).

Revelation 15/16 tells how the earth was devastated by the pouring out of the seven last plagues. The sea, rivers and streams have become like the blood of a dead man, the cities are devastated, and the islands and mountains are gone. According to Revelation 20, this desolate state of the earth will last for a thousand years. At the end of these thousand years, the holy city, in which the followers of Jesus were throughout the period, will come down from heaven like an adorned bride. It is the beginning of the new creation of the earth. God will create everything anew to set up paradise on earth again.

 Revelation 21: 3-4And I heard a great voice from the throne saying, Behold, the tabernacle of God with the people! And he will dwell with them, and they will be his people, and he himself, God with them, will be their God; and God will wipe away all the tears from their eyes, and there will be no more death, neither will there be sorrow, nor outcry, nor pain; because the first has passed.
  The holy city that comes out of heaven from God will be the new abode of God. God will dwell with the people on the new earth. The holy city is the tabernacle of God, of which Jesus wrote in John 14: 2:

There are many apartments in my father's house. If it were not so, would I have said to you: I am going to prepare the place for you?

According to Revelation 22: 3, both the throne of God and the throne of Jesus are on the new earth. Jesus will be the God of the redeemed, because "God with them" indicates the name Immanuel, which means "God with us". According to Isaiah 7:14, this Immanuel is none other than Jesus. Jesus will live in the midst of the redeemed in the new earth. He gave his life for each individual and by becoming man and hiding his divinity under human nature (cf. Philippians 2: 7), he was forever connected to humanity. The earth was the central battleground in the universe. Even the angels were probably more interested in our earth than in any other, because after all there was more joy in heaven over every sinner who had repented than over 99 righteous people (cf. Luke 15: 7).

Also, God will wipe away all tears by removing all causes for them. There will be no more death, suffering and pain, for the first earth that was under the curse of sin is past.

 Revelation 21: 5-8And he who sat on the throne said, See, I am making everything new! And he said: Write, for these words are true and certain! And he said to me, It has happened. I am the alpha and omega, the beginning and the end. I will give free of charge to the thirsty from the spring of living water. He who overcomes will inherit it all, and I will be his God and he will be my son. But the figs and the unbelievers and the wicked and the murderers and the fornicators and the sorcerers and the idolaters and all the liars, their part will be in the lake that burns with fire and brimstone; this is the second death.
  According to Revelation 22:12, 13 Jesus is the Alpha and Omega, the beginning and the end. Jesus will make everything new. That does not mean that he will create a new earth, but rather that he will make our earth new. The one through whom our earth was created for the first time (cf. Jesus as Creator) will cleanse it of the consequences of sin and make everything new. We can rely on these words because they are certain.

The overcomers will inherit the new earth (Galatians 3:29):

But if you belong to Christ, then you are Abraham's sons and heirs according to the promise.

Whoever belongs to Jesus is a child of Abraham and consequently the promise is made to him to inherit the whole earth (cf. Romans 4:13). He who overcomes should inherit everything, i.e. whoever belongs to Jesus is an overcomer.

Note: Whoever recognizes that he is justified as a sinner through Jesus (cf. Romans 1:17) and that this righteousness is a gift that is attributed to him in an undeserved way (cf. Romans 3.28), receives one whole new relationship to the law. According to Romans 3:20, knowledge of sin comes through the law and leads the sinner directly to Jesus, his Redeemer. Since one recognizes that one's own transgressions brought the Son of God to the cross, one naturally wants to keep his commandments out of love for Jesus (cf. John 14:15). Of course, one cannot keep these commandments by oneself, but Jesus sanctifies the believer through the Holy Spirit and through this one becomes a conqueror of sin (cf. Revelation 12:11).

For all other people who have not accepted Jesus as their personal savior, only the second death remains. According to Revelation 20:14, the second death means the final annihilation, which has an eternal effect.

Because we now know that the Bible predicts this, let us accept the gift of salvation through Jesus Christ today so that we can be with him on the new earth.

 Revelation 21: 9-11And one of the seven angels, who had the seven bowls with the last seven plagues, came to me and spoke to me, saying, Come, I will show you the woman, the bride of the Lamb. And he led me in the spirit to a great and high mountain and showed me the holy city of Jerusalem, coming down out of heaven from God, which had the glory of God; its light was like the most precious stone, a jasper, clear as crystal;
  One of the seven angels who had previously shown John the whore in Revelation 17 now shows him holy Jerusalem, the bride of the Lamb. In order to be able to see the city, Johannes is caught up on a high mountain. Let us now consider Galatians 4:26, 27:

But the Jerusalem that is above is free; this is our mother. Because it is written (Isaiah 54: 1): "Be happy, you sterile, who you do not bear! Break out in jubilation and exult, who are not pregnant. For the lonely has many more children than the husband. "

Paul calls heavenly Jerusalem our mother. To this end, he appeals to Isaiah and thus expresses that the Old Testament Jerusalem has far fewer children than the heavenly Jerusalem. If the holy city is the mother, Jesus is our eternal father according to Isaiah 9: 5, then we are the children. If we now apply this to the wedding of the Lamb (cf. Matthew 22), then Jesus is the bridegroom, the holy city the bride and the followers of Jesus are the wedding guests. The time of the wedding is when Jesus begins his reign, when he receives the kingdom from the Father.

 Revelation 21: 12-21It had a great and high wall, and had twelve gates and on the gates twelve angels and names written on them, namely the names of the twelve tribes of the Israelites: three gates from the east, three gates from the north, three gates from the south, three gates from the west . And the wall of the city had twelve foundation stones, and on them the twelve names of the twelve apostles of the Lamb. And whoever talked to me had a measuring stick, a golden pipe, to measure the city and its gates and its wall. And the city is square, and its length is as great as its width. And he measured the city with the pipe: twelve thousand stadia. The length and width and height of the city are the same. And he measured its wall: a hundred and forty-four cubits by the measure of a man, which the angel used. And its masonry was made of jasper and the city of pure gold, like pure glass. And the foundation stones of the wall around the city were adorned with all kinds of precious stones. The first cornerstone was a jasper, the second a sapphire, the third a chalcedony, the fourth an emerald, the fifth a sardonyx, the sixth a sarder, the seventh a chrysolite, the eighth beryl, the ninth a topaz, the tenth a Chrysoprase, the eleventh a hyacinth, the twelfth an amethyst. And the twelve gates were twelve pearls, each gate was made of a single pearl, and the town square was made of pure gold like translucent glass.
  In these verses the holy city is described to us, the new Jerusalem. There isn't much to say about this city except that John must have found it very difficult to describe in words the glory of the city.

It is interesting that the gemstones represent the colors of the rainbow. It seems a bit irritating that the width, length and height of the city seem to be the same. Biblical interpreters see the Greek word for “equal” as meaning “proportionate”. The result would be that the height of the city is in proportion to its length and width. This also fits the description of the wall, as its height is explicitly stated, which would not make sense in a cube-shaped city.

The names of the twelve apostles indicate that it is a Christian city and the names of the twelve tribes indicate that it is not natural Israel, but spiritual Israel, which includes all of Jesus' followers.

 Revelation 21: 22-26And I saw no temple in it; for the Lord Almighty God is their temple, he and the Lamb. And the city does not need a sun or a moon to shine on it; for the glory of God illuminates them, and their lamp is the Lamb. And the peoples will walk in their light; and the kings of the earth will bring their glory into them. And its gates are not closed during the day; 'Cause there won't be a night And the splendor and the riches of the nations will be brought into them.
  There will be no more temples in the holy city. The heavenly temple (cf. The heavenly sanctuary) served man's plan of salvation. It included the intercession of Jesus and the cleansing of the sanctuary from sins (cf. The Judgment). But since sin will be destroyed forever through the creation of the new earth, there is no longer any need for a sanctuary. Sacrifices, gifts, and all of Jesus' mediating work ended forever.

However, it was the case that in the Old Testament the sanctuary was not only used for worship purposes, but it was also the adornment of the city. Since there will no longer be a sanctuary on the new earth, God himself will be the glory of the new city.

Neither will there be any night in the holy city when the glory of God will illuminate the city. But that is not to say that there will be no more night on the new earth. The passage only says that there will be no night in the holy city.

Note: The kings of the new earth are not the kings of our earth today. Since the peoples of the new earth will rule for all time according to Revelation 22: 5, they are the kings of the new earth.

 Revelation 21:27And nothing unclean will enter it, and no one who acts abominations or lies, but only those who are written in the Lamb's book of life.
  The Bible clearly states that not everyone will come to the new earth. Only those who are in the book of life are allowed to be on the new earth. According to Revelation 3: 5, however, the book of life contains the overcomers who receive the garment of the righteousness of Jesus. Whoever overcomes through Jesus and lets himself be given the righteousness of Jesus, can be certain that he will be redeemed.
