2 Corinthians 6:14-18

Do not be yoked together with those who do not believe. For what partnership is there between righteousness and lawlessness? Or what fellowship does light have with darkness? What agreement does Christ have with Belial? Or what does a believer have in common with an unbeliever? And what agreement does the temple of God have with idols? For we are the temple of the living God, as God said: I will dwell and walk among them, and I will be their God, and they will be my people. Therefore, come out from among them and be separate, says the Lord; do not touch any unclean thing, and I will welcome you. And I will be a Father to you, and you will be sons and daughters to me, says the Lord Almighty.
