Unequally yoked

2 Corinthians 6:14-18
[14]Do not try to work together as equals with unbelievers, for it cannot be done. How can right and wrong be partners? How can light and darkness live together?
[15]How can Christ and the Devil agree? What does a believer have in common with an unbeliever?
[16]How can God’s temple come to terms with pagan idols? For we are the temple of the living God! As God himself has said: “I will make my home with my people and live among them; I will be their God, and they shall be my people.”
[17]And so the Lord says, “You must leave them     and separate yourselves from them. Have nothing to do with what is unclean, and I will accept you.
[18]I will be your father, and you shall be my sons and daughters, says the Lord Almighty.”
