And what agreement has the temple of God with idols? for you are the temple of the living God; as God has said,
I will dwell in them, and walk in them; and I will be their God, and they shall be my people.

It is obvious that the things Paul lists are opposites and that we are to flee from the ones and cling to the others. No one can serve two masters. Christ has proclaimed that we should go away from the devil, who wants to represent himself falsely as God. He has promised us eternal life, so we should be strangers to the treachery and wrongheadedness of unbelievers. He has forbidden the worship of idols because they are incompatible with the temple of God. We are temples of the living God. There is nothing more damaging to us than idols, because they tempt us to depart from our faith in the one true God. Commentary on Paul’s Epistles.
