2 Corinthians 6:14-18; 2 Corinthians 7:1

14 Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness?

15 Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever?

16 Or what agreement has the temple of God with idols? For we are the temple of the living God; just as God said, "I WILL DWELL IN THEM AND WALK AMONG THEM; AND I WILL BE THEIR GOD, AND THEY SHALL BE MY PEOPLE.

17 "Therefore, COME OUT FROM THEIR MIDST AND BE SEPARATE," says the Lord . "AND DO NOT TOUCH WHAT IS UNCLEAN; And I will welcome you.

18 "And I will be a father to you, And you shall be sons and daughters to Me," Says the Lord Almighty.

1 Therefore, having these promises, beloved, let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God.
