2 Peter 3:7-9

7But by the same word the present heavens and earth have been reserved for fire, by being kept for the day of judgment and destruction of the ungodly.

8Now, dear friends, do not let this one thing escape your notice, that a single day is like a thousand years with the Lord and a thousand years are like a single day.

9The Lord is not slow concerning his promise, as some regard slowness, but is being patient toward you, because he does not wish for any to perish but for all to come to repentance.
