Then I heard what sounded like a great multitude, like the roar of rushing waters and like loud peals of thunder, shouting:
“Hallelujah!
For our Lord God Almighty reigns.
Let us rejoice and be glad
and give him glory! - Rev. 18:6-8 NIV
Then John saw heaven standing open and a white horse, whose rider is called Faithful and True. With justice he judges and makes war. His eyes are like blazing fire, and on his head are many crowns. He has a name written on him that no one knows but he himself. He is dressed in a robe dipped in blood, and his name is the Word of God. The armies of heaven were following him, riding on white horses and dressed in fine linen, white and clean. Out of his mouth comes a sharp sword with which to strike down the nations. “He will rule them with an iron scepter.” He treads the winepress of the fury of the wrath of God Almighty. On his robe and on his thigh he has this name written:
KING OF KINGS AND LORD OF LORDS. -Rev. 19:11-16
John saw Satan subdued for a thousand years while Christ reigned. When Satan was released, there wais one final battle before he is thrown into the lake of burning fire to be tormented for ever and ever. Each person was judged and according to what they have done, whether or not their name was recorded in the book of life. Those whose names were not in the book of life were thrown into the lake of fire along with death and Hades.
And finally, John saw a new heaven and new earth and a loud voice called 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. 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.”
He who was seated on the throne said, “I am making everything new!” Then he said, “Write this down, for these words are trustworthy and true.” - Rev 21:3-5 NIVThe words are trustworthy and true. There will be a new heaven and a new earth, a new city, but one without a temple because the Lord God Almighty and the Lamb are its temple. The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp. The nations will walk by its light, and the kings of the earth will bring their splendor into it. On no day will its gates ever be shut, for there will be no night there. The glory and honor of the nations will be brought into it. Nothing impure will ever enter it, nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb’s book of life. - Rev 21:22-27 NIV
There will be no night, there will be no sin, because only those who have been cleansed by the blood of the Lamb, only those who have their names written in the Lamb's book of life, will be there. The one whose name is King of Kings and Lord of Lords, the Alpha and Omega, the First and the Last, the Beginning and the End, the one who is called Faithful and True has declared it so.
