You have to live or work among others but don’t be yoked with them.
Read: 2 Corinthians 6:14-16
14 Don’t team up with those who are unbelievers. How can righteousness be a partner with wickedness? How can light live with darkness? 15 What harmony can there be between Christ and the devil? How can a believer be a partner with an unbeliever? 16 And what union can there be between God’s temple and idols? For we are the temple of the living God. As God said:
“I will live in them
and walk among them.
I will be their God,
and they will be my people.
