2 Pedro 3

8 But do not forget this one thing, beloved, that one day is with the Lord as a thousand years, and a thousand years as one day.

9 The Lord is not slow concerning his promise, as some count slowness; but is patient with you, not wishing that any should perish, but that all should come to repentance.

10 But the day of the Lord will come as a thief; 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 disclosed.
