8 However, my friends, don’t forget this one thing: that for the Lord a day is like a thousand years, and a thousand years is like a day.3:8. See Psalms 90:4. 9 The Lord is not delaying the fulfillment of his promise, as some define delay, but he is being very patient with you. He doesn’t want anyone to be lost, but everyone to come and repent.
10 However, the day of the Lord will come, unexpectedly like a thief. The heavens will explode with a thunderous roar, and the elements3:10. It is not clear exactly what these "elements" refer to. will be destroyed as they are burned up. The earth and everything in it will vanish.3:10. Or "will be seen for what it is." 11 Since everything is going to be destroyed in this way, what kind of people should you be? You should be living lives that are pure, dedicated to God, 12 waiting expectantly and being eager for the coming of the day of God. That day the heavens will catch fire and be destroyed, and the elements will melt in the heat. 13 But as for us, we are looking for new heavens and a new earth that God has promised where everything is good and right.3:13. Or "where righteousness dwells."
