2 Peter 3:6-8

Revised Standard Version Catholic Edition

⁶ through which the world that then existed was deluged with water and perished. ⁷ But by the same word the heavens and earth that now exist have been stored up for fire, being kept until the day of judgment and destruction of ungodly men.

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