2 Peter 3

8 But let not this one thing be hidden from you, beloved, that one day with the Lord is as a thousand years, and a thousand years as one day.

9 The Lord does not delay his promise, as some account of delay, but is longsuffering towards you, 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 which the heavens will pass away with a rushing noise, and the elements, burning with heat, shall be dissolved, and the earth and the works in it shall be burnt up.
