2 Corinthians 6:14-17

14 Stop forming inappropriate relationships with unbelievers. Can right and wrong be partners? Can light have anything in common with darkness?
15 Can Christ agree with the devil? Can a believer share life with an unbeliever?
16 Can God's temple contain false gods? Clearly, we are the temple of the living God. As God said, "I will live and walk among them. I will be their God, and they will be my people."
17 The Lord says, "Get away from unbelievers. Separate yourselves from them. Have nothing to do with anything unclean. Then I will welcome you."
