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. 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. 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. 11 Since all these things are to melt away in this manner, what sort of people must you be, conducting your lives in holiness and godliness, 12 while waiting for and hastening the coming of the day of God? Because of this day, the heavens will be burned up and dissolve, and the celestial bodies will melt away in a blaze! 13 But, according to his promise, we are waiting for new heavens and a new earth, in which righteousness truly resides.
§ Rabbi Alexandri says: Rabbi Yehoshua ben Levi raises a contradiction in a verse addressing God’s commitment to redeem the Jewish people. In the verse: “I the Lord in its time I will hasten it” (Isaiah 60:22), it is written: “In its time,” indicating that there is a designated time for the redemption, and it is written: “I will hasten it,” indicating that there is no set time for the redemption. Rabbi Alexandri explains: If they merit redemption through repentance and good deeds I will hasten the coming of the Messiah. If they do not merit redemption, the coming of the Messiah will be in its designated time.
