See, the Songs of Ascents give us a glorious vision of the new Jerusalem — end-of-time reality when God will be with his people and his Messiah will reign, but, it’s still a vision.
It’s not reality now. Reality now is still in Meshech. For now we still live in Kedar. We’re looking to this new Jerusalem; we’re living our lives with our eyes set there, but we’re not there yet. And we should remember this.
