2 Peter 3:7-9

7By the same word, the present heavens and earth are stored up for fire, being kept for the day of judgment and destruction of the ungodly.

8Dear friends, don’t overlook this one fact: With the Lord one day is like a thousand years, and a thousand years like one day.

9The Lord does not delay his promise, as some understand delay, but is patient with you, not wanting any to perish but all to come to repentance.
