2 Peter 3:7-9

7But by the same word the present heavens and earth are being reserved for fire—kept until the Day of Judgment and the destruction of ungodly people.

8But don’t forget this one thing, loved ones, that with the Lord one day is like a thousand years, and a thousand years are like one day.

9The Lord is not slow in keeping His promise, as some consider slowness. Rather, He is being patient toward you—not wanting anyone to perish, but for all to come to repentance.
