2 Peter 3:8-10

3:8 Now, 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. 3:9 The 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. 3:10 But the day of the Lord will come like a thief; when it comes, the heavens will disappear with a horrific noise, and the celestial bodies will melt away in a blaze, and the earth and every deed done on it will be laid bare.
