2 Peter 3:13-15

13But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells. 14So then, dear friends, since you are looking forward to this, make every effort to be found spotless, blameless and at peace with him. 15Bear in mind that our Lord’s patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him.
