2 Peter 3:4-9New Revised Standard Version (NRSV)
4 and saying, “Where is the promise of his coming? For ever since our ancestors died,[a] all things continue as they were from the beginning of creation!” 5 They deliberately ignore this fact, that by the word of God heavens existed long ago and an earth was formed out of water and by means of water, 6 through which the world of that time was deluged with water and perished. 7 But by the same word the present heavens and earth have been reserved for fire, being kept until the day of judgment and destruction of the godless.
8 But do not ignore this one fact, beloved, that with the Lord one day is like a thousand years, and a thousand years are like one day. 9 The Lord is not slow about his promise, as some think of slowness, but is patient with you,[b] not wanting any to perish, but all to come to repentance.
