The New Jerusalem: One Big Flying Saucer?

'He took me in spirit to a great, high mountain and showed me the holy city Jerusalem coming down out of heaven from God. 11 It gleamed with the splendor of God. Its radiance was like that of a precious stone, like jasper, clear as crystal. 12 It had a massive, high wall, with twelve gates where twelve angels were stationed and on which names were inscribed, [the names] of the twelve tribes of the Israelites.  13 There were three gates facing east, three north, three south, and three west. 14 The wall of the city had twelve courses of stones as its foundation, on which were inscribed the twelve names of the twelve apostles* of the Lamb! 15 * The one who spoke to me held a gold measuring rod to measure the city, its gates, and its wall. 16 The city was square, its length the same as [also] its width. He measured the city with the rod and found it fifteen hundred miles* in length and width and height. 17 He also measured its wall: one hundred and forty-four cubits* according to the standard unit of measurement the angel used. 18 * The wall was constructed of jasper, while the city was pure gold, clear as glass. 19 The foundations of the city wall were decorated with every precious stone; the first course of stones was jasper, the second sapphire, the third chalcedony, the fourth emerald, 20 the fifth sardonyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh hyacinth, and the twelfth amethyst. 21 The twelve gates were twelve pearls, each of the gates made from a single pearl; and the street of the city was of pure gold, transparent as glass.  22  I saw no temple in the city, for its temple is the Lord God almighty and the Lamb. 23 The city had no need of sun or moon to shine on it,  for the glory of God gave it light, and its lamp was the Lamb. 24 The nations will walk by its light,* and to it the kings of the earth will bring their treasure. 25 During the day its gates will never be shut, and there will be no night there. 26 The treasure and wealth of the nations will be brought there, 27 but nothing unclean will enter it, nor any[one] who does abominable things or tells lies. Only those will enter whose names are written in the Lamb’s book of life.'
