14Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? 15Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever? 16Or 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 in them and walk among them; And I will be their God, and they shall be My people. 17Therefore, come out from their midst and be separate, says the Lord. And do not touch what is unclean; And I will welcome you.
– II Corinthians 6:14-17 (NASB)
