2 Peter 3:6-8

New Revised Standard Version, Anglicised

⁶ through which the world of that time was deluged with water and perished. ⁷ But by the same word the present heavens and earth have been reserved for fire, being kept until the day of judgement and destruction of the godless.

⁸ But do not ignore this one fact, beloved, that with the Lord one day is like a thousand years, and a thousand years are like one day.
