2 Corinthians 6:14-18

Don’t be unequally yoked with unbelievers, for what fellowship do righteousness and iniquity have? Or what fellowship does light have with darkness? What agreement does Messiah have with Belial? Or what portion does a believer have with an unbeliever? What agreement does a temple of God have with idols? For you are a temple of the living God. Even as God said, “I will dwell in them and walk in them. I will be their God and they will be my people.” Therefore “‘Come out from among them, and be separate,’ says the Lord. ‘Touch no unclean thing. I will receive you. I will be to you a Father. You will be to me sons and daughters,’ says the Lord Almighty.”
