2 Corinthians 6:14-18 - Do Not Become Unevenly Yoked With Unbelievers
14 Stop forming intimate and inconsistent relations with unbelievers. What partnership can right-doing have with law-breaking, or how can light participate with darkness? 15 What harmony exists between Christ and Belial, or what is common between a believer and an unbeliever? 16 And what agreement can a temple of God make with idols? For we are the temple of the living God, just as God said: "I will live in them and walk in them, and I will be their God and they will be my people." 17 Therefore: "'Come out of company with them, and separate from them,' the Lord has said, 'And stop touching what is unclean; then I will welcome you, 18 I will be a Father to you, and you will be sons and daughters of mine,' The Lord Almighty said."
