2 Peter 3:8-14; Revelation 21:1-6

8 But you must not forget this one thing, dear friends: A day is like a thousand years to the Lord, and a thousand years is like a day. 9 The Lord isn’t really being slow about his promise, as some people think. No, he is being patient for your sake. He does not want anyone to be destroyed, but wants everyone to repent. 10 But the day of the Lord will come as unexpectedly as a thief. Then the heavens will pass away with a terrible noise, and the very elements themselves will disappear in fire, and the earth and everything on it will be found to deserve judgment. 11 Since everything around us is going to be destroyed like this, what holy and godly lives you should live, 12 looking forward to the day of God and hurrying it along. On that day, he will set the heavens on fire, and the elements will melt away in the flames. 13 But we are looking forward to the new heavens and new earth he has promised, a world filled with God’s righteousness. 14 And so, dear friends, while you are waiting for these things to happen, make every effort to be found living peaceful lives that are pure and blameless in his sight.
1 Then I saw a new heaven and a new earth, for the old heaven and the old earth had disappeared. And the sea was also gone. 2 And I saw the holy city, the new Jerusalem, coming down from God out of heaven like a bride beautifully dressed for her husband. 3 I heard a loud shout from the throne, saying, “Look, God’s home is now among his people! He will live with them, and they will be his people. God himself will be with them. 4 He will wipe every tear from their eyes, and there will be no more death or sorrow or crying or pain. All these things are gone forever.” 5 And the one sitting on the throne said, “Look, I am making everything new!” And then he said to me, “Write this down, for what I tell you is trustworthy and true.” 6 And he also said, “It is finished! I am the Alpha and the Omega—the Beginning and the End. To all who are thirsty I will give freely from the springs of the water of life.
