Mother in heaven as part of image of God

Today I met 3 Korean students preaching about the image of God. Which is said, supposed to be 2 images: Father of God, and Mother of God.

Genesis 1:26-27

26 Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, ^[a] and over all the creatures that move along the ground."

27 So God created man in his own image,
in the image of God he created him;
male and female he created them.

It is written there that the bible uses plural when referring to himself (or themselves), using the word us and our. So the image of God consists of 2 images. That is the Father of God and also the Mother of God, just like how everything else is created.

Gal 4:26

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

Rev 21:9-10

9One 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." 10And 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.

From here it is said that the mother of God or the mother of heaven is actually Jerusalem, who is the wife of the Lamb. And Jesus is the Lamb.

Rev 22:17

17The Spirit and the bride say, "Come!" And let him who hears say, "Come!" Whoever is thirsty, let him come; and whoever wishes, let him take the free gift of the water of life.

So you should go to Jerusalem and take the free gift of the water of life.
