The Jerusalem of the future (Revelation, 21, 1-4; 10-14)
Then I saw a new heaven and a new earth, the first heaven and the first earth had disappeared now, and there was no longer any sea. I saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared as a bride dressed for her husband.
Then I heard a loud voice call from the throne. Look, here God lives among human beings. He will make his home among them; they will be his people, and he will be their God, God-with-them. He will wipe away all tears from their eyes; there will be no more death, and no more mourning or sadness or pain. The world of the past has gone.
... In the spirit, he carried me to the top of a very high mountain, and showed me Jerusalem, the holy city, coming down out of heaven from God. It had all the glory of God and glittered like some precious jewel of crystal-clear diamond. Its wall was of a great height and had twelve gates; at each of the twelve gates there was an angel, and over the gates were written the names of the twelve tribes of Israel; on the east there were three gates, on the north three gates, on the south three gates, and on the west three gates. The city walls stood on twelve foundation stones, each one of which bore the name of one of the twelve apostles of the Lamb.
