2 Peter 3:11, 14, 17

Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives

So then, dear friends, since you are looking forward to this, make every effort to be found spotless, blameless and at peace with him.

Therefore, dear friends, since you have been forewarned, be on your guard so that you may not be carried away by the error of the lawless and fall from your secure position.
