2 Corinthians 6:14-18
14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you.
18 And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.

The Epistle of 2nd Corinthians chapter 4:4
In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.
The Epistle of 1st Corinthians 5:12What business of mine is it to judge those outside the church ? Are you not to judge those inside?
Also, I would suggest you research the context of that full chapter of chapter 6 in the Book of 2nd Corinthians as it is that of Paul's church epistles to the churches in Corinth. And perhaps choose to learn about the culture of Corinth as well.
Church Epistles are those letters Paul wrote guiding the churches he founded and oversaw.
That is not God's edict. That is Paul's management.
Before judging those whom Jesus died for, all people in the world, you might consider that those who identify as Christian argue against Jesus teachings as to how to follow his commands.
15. “If you love me, you will keep my commandments." The Book of John chapter 14
As the Saint Apostle Paul said, we are to judge those in the church. Why occupy our time with those outside? The Great Commission was exampled by Christ and His Apostles and His guidance to them. If they encountered a village or people not open to receive the Gospel, they were told to kick the dust from their feet and move on.
Jesus didn't say to call those people a name, or feel hatred for them. And why would he? Jesus was God on Earth and all that is created, including unbelievers, are of and from God.
