1 Peter 1:14-16, 22-23

As obedient children, do not conform to the evil desires you had when you lived in ignorance. But just as he who called you is holy, so be holy in all you do; for it is written: “Be holy, because I am holy.”

Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart. For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.
