The New Jerusalem = realm of God = Eternity / Eternal Life = The Mystery of GodThe New Jerusalem descends intact (UNcreated,) having always been for it is God's dwelling, not man's ... and thus the sign or allegory is lost on materialistic minded interpreters.The glory of the nations are brought into the City, but note that as that is revealed, there is no occupants of the City. There are streets of gold, but nobody walking upon them ... rather the City IS the people ... no man will walk upon these streets (if we follow the allegory) ... rather the men of the City ARE the street, themselves. ... even the individual bricks of the walls ... for John did see the names of the patriarchs on the actual bricks and structures.Therefore we know that in the dwelling of God (New Jerusalem) it is us (His servants) that make up the place in which He dwells ... and it is right to say that He lives IN us on that day in complete fulfillment for we are that of which His dwelling is made ... the individual parts and places of the City, Itself.Greater still is the mystery that is yet to be revealed than what was revealed to John in that allegory ... Yet to those that meditate and allow the Lord to teach them what the City means, a treasure of understanding can come ... for all of God's truths are simple and pure ... yet immeasurably deep and inexhaustible.
