2 Peter 3:8–13
8But 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.
9The 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.
10But 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.
11Therefore, since all these things will be destroyed like this, what kind of people ought you to be in holy living and godliness,
12looking for and earnestly desiring the coming of the day of God, which will cause the burning heavens to be dissolved, and the elements will melt with fervent heat?
13But, according to his promise, we look for new heavens and a new earth, in which righteousness dwells.
