evilness of a particular generation. On the other hands, if a generation is not evil but lover of God, shall not that generation still hope for miracle from God. In the last day, or the final generation might expect new Jerusalem to come down out of heaven from God and onto the earth, no more tears, no more pains, no more death, are these not miracle of God, then mankind has to use his own wisdom and hands to fulfill these final goals.

Revelation 21
2 I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband.
3 And I heard a loud voice from the throne saying, "Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God.
4 He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away."
