2 Corinthians 6:14-18

Don't join together with people who don't believe—for what connection does goodness have with wickedness? What do light and darkness have in common? How could Christ and the devil ever agree? How could a believer and an unbeliever share together? What compromise could the Temple of God make with idols? For we are a temple of the living God, just as God said: “I will live in them and walk among them. I will be their God, and they will be my people.” “So leave them, and separate yourselves from them, says the Lord. Don't touch anything that is unclean, and I will accept you.” “I will be like a Father to you, and you will be sons and daughters to me, says the Lord Almighty.”
