God`s word says that He is Spirit and that He does NOT come down with the city.
He does come down:
John 14:23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and
we will come unto him, and make our abode with him.
Rev 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Rev 21:3 And I heard a great voice out of heaven saying,
Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and
God himself shall be with them, and be their God.
Rev 21:10 And he carried me away in the spirit to a great and high mountain, and shewed me that great city, the holy Jerusalem, descending out of heaven from God,
Rev 21:11 Having the glory of God: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal;
Rev 21:12 And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel:
Rev 21:13 On the east three gates; on the north three gates; on the south three gates; and on the west three gates.
Rev 21:14 And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.
Rev 21:15 And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.
Rev 21:16 And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.
Rev 21:17 And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.
Rev 21:18 And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass.
Rev 21:19 And the foundations of the wall of the city were garnished with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald;
Rev 21:20 The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst.
Rev 21:21 And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass.
Rev 21:22 And I saw no temple therein: for
the Lord God Almighty and the Lamb are the temple of it.
