2 Peter 3:8–10

But don’t forget this one thing, beloved, that one day is with the Lord as a thousand years, and a thousand years as one day. The Lord is not slow concerning his promise, as some count slowness; but he is patient with us, not wishing that anyone should perish, but that all should come to repentance. But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will be dissolved with fervent heat; and the earth and the works that are in it will be burned up.
