Once read a story ,written actually somewhere here at this land ,I live ...
Really weird story ....Ending like ...
21:2And I saw the holy city, new Jerusalem, coming down out of heaven of God, made ready as a bride adorned for her husband.
.......
21:10And he carried me away in the Spirit to a mountain great and high, and showed me the holy city Jerusalem, coming down out of heaven from God,
21:11having the glory of God: her light was like unto a stone most precious, as it were a jasper stone, clear as crystal:
21:12having a wall great and high; having 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:
21:13on the east were three gates; and on the north three gates; and on the south three gates; and on the west three gates.
21:14And the wall of the city had twelve foundations, and on them twelve names of the twelve apostles of the Lamb.
21:15And he that spake with me had for a measure a golden reed to measure the city, and the gates thereof, and the wall thereof.
21:16And the city lieth foursquare, and the length thereof is as great as the breadth: and he measured the city with the reed, twelve thousand furlongs: the length and the breadth and the height thereof are equal.
21:17And he measured the wall thereof, a hundred and forty and four cubits, according to the measure of a man, that is, of an angel.
21:18And the building of the wall thereof was jasper: and the city was pure gold, like unto pure glass.
21:19The foundations of the wall of the city were adorned with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;
21:20the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; the twelfth, amethyst.
21:21And the twelve gates were twelve pearls; each one of the several gates was of one pearl: and the street of the city was pure gold, as it were transparent glass.
21:22And I saw no temple therein: for the Lord God the Almighty, and the Lamb, are the temple thereof.
21:23And the city hath no need of the sun, neither of the moon, to shine upon it: for the glory of God did lighten it, and the lamp thereof is the Lamb.
21:24And the nations shall walk amidst the light thereof: and the kings of the earth bring their glory into it.
21:25And the gates thereof shall in no wise be shut by day (for there shall be no night there):
21:26and they shall bring the glory and the honor of the nations into it:
21:27and there shall in no wise enter into it anything unclean, or he that maketh an abomination and a lie: but only they that are written in the Lamb's book of life.
Anyway ....
I'm not planning on getting aboard on any ship./..
