How Will I Know?

2 Corinthians 6:14-18 NASB
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.
