2 Peter 3:12-13

12 looking for and hastening the coming of the day of God, because of which the heavens will be destroyed by burning, and the elements will melt with intense heat! 13 But according to His promise we are looking for new heavens and a new earth, in which righteousness dwells.

Along with the effort of trying to live in holiness and godliness (v. 11), we ought to live in expectation of His coming with eager desire for it; because on the other side of the great destruction is all that is new—a new heaven and earth which is totally righteous.
