The Bible is a testimony of Christ who came to this earth to save us. We can recognize the true God only through the prophecies of the Bible.
Through the prophecy of Revelation, salvation can only be obtained by meeting the Holy Spirit and the Bride, who are the Saviors in this age of the Holy Spirit.

Revelation 22:17 The Spirit and the bride say, “Come!” And let the one who hears say, “Come!” Let the one who is thirsty come; and let the one who wishes take the free gift of the water of life.

The Bible prophesies that the Holy Spirit and the Bride give the water of life, that is, eternal life.
As everyone knows, the Holy Spirit is the Second Coming Jesus. Then, who is the Bride of the Holy Spirit?
Since the bride is also the God who gives us the water of life, we must know who the bride is.

Revelation 21:9 ~ 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.

The same Revelation tells us that the Bride of the Holy Spirit is Heavenly Jerusalem.
So, what is the relationship between Heavenly Jerusalem and us?

Galatians 4:26 But the Jerusalem that is above is free, and she is our mother.

The Bible tells us that heavenly Jerusalem is our mother.
In other words, Heavenly Jerusalem, the bride who comes with the Second Coming Jesus, who is the Holy Spirit and gives us the blessing of eternal life, is the mother of our souls.

We who live in this last age of the Holy Spirit can receive the blessings and salvation of eternal life only when we become children of Heavenly Jerusalem Mother.
