1 Peter 1:14-16, 22-23

So you must live as God’s obedient children. Don’t slip back into your old ways of living to satisfy your own desires. You didn’t know any better then. But now you must be holy in everything you do, just as God who chose you is holy. For the Scriptures say, “You must be holy because I am holy.”

You were cleansed from your sins when you obeyed the truth, so now you must show sincere love to each other as brothers and sisters. Love each other deeply with all your heart. For you have been born again, but not to a life that will quickly end. Your new life will last forever because it comes from the eternal, living word of God.
