2 Peter 3:8-10 NIV

[8] But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. [9] The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance. [10] But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.
