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.”

7:1 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.
