Heavenly Mother, the Throne of the LORD

In the Old Testament, I always read where it was mentioned about an "Ark of the Covenant". I decided to ask the members of the World Mission Society Church of God about the importance of the Ark of the Covenant mentioned many times in the bible. Of course my question was answered through the bible which is what I love most about this Church. The last verse they took me to which stuck most in my head was Jeremiah 3:16-17 which says; “In those days, when your numbers have increased greatly in the land," declares the LORD, "men will no longer say, 'The ark of the covenant of the LORD.' It will never enter their minds or be remembered; it will not be missed, nor will another one be made. At that time they will call Jerusalem The Throne of the LORD, and all nations will gather in Jerusalem to honor the name of the LORD. No longer will they follow the stubbornness of their evil hearts."
God said that in the last days, men will no longer speak about the ark of the covenant of the LORD. Why is that? Verse 17 says, at that time (in the last days), they will call Jerusalem the Throne of the LORD (Ark of the Covenant). This means that in the last days, men will come to Jerusalem to gather there and to honor the Name of the LORD. Then, who is the Jerusalem in the bible men must come to in the last days? Galatians 4:26 says, but the Jerusalem that is above is free and she is our MOTHER. That's right, the Jerusalem mentioned in the book of Jeremiah, the Throne of the LORD is God the Mother in these days that we're living in. Just wanted to share this with the people here and hope you're as excited as I am after realizing this. I, like always, will stick to studying and learning more.
