2 Pedro 3

8 But, beloved, be not ye ignorant of this one thing, 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 (tho' some men count it slowness) but is long-suffering toward us, not willing that any should perish, but that all should come to repentance.

10 But the day of the Lord will come as a thief in the night, in which the heavens shall pass away with a great noise, the elements shall melt with fervent heat, and the earth, and the works that are therein, shall be burnt up.
