I warn everyone who hears the words of the prophecy of this book: If anyone adds anything to them, God will add to him the plagues described in this book. And if anyone takes words away from this book of prophecy, God will take away from him his share in the tree of life and in the holy city, which are described in this book.(Rev 22:18-19)

At the end of the Bible, God said that if you do not do as the prophecy of this book says, you will not be able to participate in the life tree and the holy castle. To not be able to advance to the life tree means that you will not be able to achieve eternal life, and to be given the privilege to participate in the holy castle means that you will not be able to enter heaven. The important point here is where the holy city dictates. To obtain salvation, you need to know where the holy city is.

I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband.And I heard a loud voice from the throne saying, "Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God.He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away."(Rev21:2-4)

One of the seven angels who had the seven bowls full of the seven last plagues came and said to me, "Come, I will show you the bride, the wife of the Lamb."And he carried me away in the Spirit to a mountain great and high, and showed me the Holy City, Jerusalem, coming down out of heaven from God.(Rev21:9-10)

John the Apostle proved that Jerusalem is the holy city that descends from heaven. When this Jerusalem comes down from heaven, God's dwelling is with the people, so that the people of God can be saved from eternal heaven.

Jerusalem, the holy city that leads us to salvation, is the our spiritual Mother.

But the Jerusalem that is above is free, and she is our mother.(Gal4:26)

In the Revelation 21, Jerusalem is "bride," or "wife of the lamb," but in Galatians, "our Mother." In this age, The savior with God the Father is our Heavenly Mother. Therefore, our salvation is completed through the Heavenly Mother.

We are the children of Jerusalem Mother. God has invited us to a heavenly wedding banquet and allowed us to participate in Jerusalem's holy glory. We are truly blessed with these privileges.
There are still many souls in the world who do not know or realize the existence of Jerusalem. We will express a lot of glory of the Jerusalem Mother to spread this blessing and quickly find the lost siblings and give joy to God.
