2 Corinthians 6:14-7:1 Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness? What accord has Christ with Belial? Or what portion does a believer share with an unbeliever? What agreement has the temple of God with idols? For we are the temple of the living God; as God said, "I will make my dwelling among them and walk among them, and I will be their God, and they shall be my people. Therefore go out from their midst, and be separate from them, says the Lord, and touch no unclean thing; then I will welcome you, and I will be a father to you, and you shall be sons and daughters to me, says the Lord Almighty." Since we have these promises, beloved, let us cleanse ourselves from every defilement of body and spirit, bringing holiness to completion in the fear of God. Paul begins this passage by telling the Corinthians that they are not to be bound together with unbelievers. The meaning behind this is that we are not to have intimate dealings with unbelievers that would place us in a position to compromise our faith. He expands on this by comparing Christ with Satan and the temple of God with idols. The conclusion is that we are to live separate from them. This does not mean we are to have no dealings with unbelievers, but rather we are to not have intimate dealings with unbelievers. Paul then says, "then I will welcome you, and I will be a father you, you shall be sons and daughters to me". Because of these promises Paul tells the Corinthians to "cleanse ourselves from every defilement of body and spirit, bringing holiness to completion in the fear of God." Cleansing ourselves from bodily and spiritual defilement is an imperative. It is something we are commanded to do. It is not optional. The purpose is to "bring holiness to completion in the fear of God." This is really a description of our sanctification. As we yield to the Spirit of God, avoiding sin and pursuing righteousness, we become more mature in our faith. We push forward to holiness. This is evidence that we are children of God.
