2 Peter 3:5-8

King James Version

⁵ For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:

⁶ Whereby the world that then was, being overflowed with water, perished:

⁷ But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.

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