1 Peter 2:9-11

But you are God’s chosen treasure —priests who are kings, a spiritual “nation” set apart as God’s devoted ones. He called you out of darkness to experience his marvelous light, and now he claims you as his very own. He did this so that you would broadcast his glorious wonders throughout the world. For at one time you were not God’s people, but now you are. At one time you knew nothing of God’s mercy, because you hadn’t received it yet, but now you are drenched with it! My divinely loved friends, since you are resident aliens and foreigners in this world, I appeal to you to divorce yourselves from the evil desires that wage war within you.
