2 Peter 3:8-12

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. 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. 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. Since everything around us is going to be destroyed like this, what holy and godly lives you should live, 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.
