"At that time they shall call Jerusalem the throne of the Lord, and all nations shall be gathered unto it, to the name of the Lord, to Jerusalem, neither shall they walk any more after the imagination of their evil heart."[Jeremiah 3:18]
We are citizens of the heavenly Jerusalem, the true, faithful, and loyal Jerusalem, the Jerusalem that recognizes God's anointed King, the Lord Jesus Christ. The false Jerusalem, the one that denies Jesus, is in bondage with all of her children.
You need to reread that scripture from Galatians. It says "the Jerusalem which now is ....". ---- meaning the Jerusalem at that time and it is true that that Jerusalem was in bondage.
But when the King returns to earth, the Jerusalem that now is will be rebuilt ---- else why pray the Lords Prayer: "thy kingdome come ... on earth as it is in heaven".
