2 Corinthians 6:14-18 NIV

[14] Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? [15] What harmony is there between Christ and Belial? Or what does a believer have in common with an unbeliever? [16] What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: “I will live with them and walk among them, and I will be their God, and they will be my people.” [17] Therefore, “Come out from them and be separate, says the Lord. Touch no unclean thing, and I will receive you.” [18] And, “I will be a Father to you, and you will be my sons and daughters, says the Lord Almighty.”
