2 Peter 3:8-14 New American Bible (Revised Edition) (NABRE)
8 [a]But do not ignore this one fact, beloved, that with the Lord one day is like a thousand years[b] and a thousand years like one day. 9 The Lord does not delay his promise, as some regard “delay,” but he is patient with you, not wishing that any should perish but that all should come to repentance. 10 But the day of the Lord will come like a thief,[c] and then the heavens will pass away with a mighty roar and the elements will be dissolved by fire, and the earth and everything done on it will be found out.
Exhortation to Preparedness.[d] 11 Since everything is to be dissolved in this way, what sort of persons ought [you] to be, conducting yourselves in holiness and devotion, 12 [e]waiting for and hastening the coming of the day of God, because of which the heavens will be dissolved in flames and the elements melted by fire. 13 But according to his promise we await new heavens and a new earth[f] in which righteousness dwells.
14 Therefore, beloved, since you await these things, be eager to be found without spot or blemish before him, at peace.
