Do not be one with this world

We gonna analyze together these verses
2 Corinthians 6:14-17
(14) Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness? (15) And what accord has Christ with Belial? Or what part has a believer with an unbeliever? (16) And what agreement has the temple of God with idols? For you are the temple of the living God. As God has said:
"I will dwell in them
And walk among them.
I will be their God,
And they shall be My people."
(17) Therefore "Come out from among them
And be separate, says the Lord.
Do not touch what is unclean,
And I will receive you."
Lets see what the Word of God has to say to us, my beloved
