Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever? Or what agreement has the temple of God with idols? For we are the temple of the living God; just as God said, “I will dwell among them and walk among them; and I will be their God and they shall be My people. Therefore, come out from their midst and be separate,” says the Lord. “Do not touch what is unclean; and I will welcome you. And I will be a father to you, and you shall be sons and daughters to Me,” says the Lord Almighty.

– The Apostle Paul
