1 Peter 1:15-17

ISV(i) 15 Instead, be holy in every aspect of your life, just as the one who called you is holy. 16 For it is written, “You must be holy, because I am holy.”
17 If you call “Father” the one who judges everyone impartially according to what they have done, you must live in reverent fear as long as you are strangers in a strange land.
