2 Corinthians 6:14-16

Mace(i) 14 Are you not become associates with infidels? but what affinity is there between virtue and vice? and what communication has light with darkness? 15 what concord can Christ maintain with Belial? what concern has a believer with an infidel? 16 and what agreement hath the temple of God with idols? for ye are the temple of the living God; as God has said, "I will dwell with, and walk among them; I will be their God, and they shall be my people.
