Read: 1 Corinthians 5:1-13
I wrote to you in my letter not to associate with sexually immoral people — not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. But now I am writing to you that you must not associate with anyone who claims to be a brother or sister but is sexually immoral or greedy, an idolater or slanderer, a drunkard or swindler. Do not even eat with such people. What business is it of mine to judge those outside the church? Are you not to judge those inside? God will judge those outside. Expel the wicked person from among you. I Corinthians 5:9-13
Paul refers to a letter that he had written to them, a letter that is lost to us. In it, Paul had evidently said something about not associating with immoral people, and the Corinthians had taken it to mean (as many Christians seem to feel today), that they were not to have anything to do with unbelievers who lived immoral lives.
I am amazed at how that very attitude which Paul was attempting to correct here in this letter has pervaded the evangelical world. I meet people who refuse to have anybody come into their homes who is not a Christian — people who want nothing to do with anybody who lives in a way that is offensive to the Lord. I remember in my early pastorate going to a couple and asking them to open their home for a Bible class. The lady looked horrified and said, Oh! I could never do that. I asked, Why not? Why, she said, people who smoke would come in. My home is dedicated to God and I am not going to have any smoking going on there.
That is a misunderstanding of the very thing Paul is talking about. We cannot avoid the world — we were sent into it. The Lord Jesus said to his disciples, Behold, I send you forth as sheep in the midst of wolves, (Matthew 10:16 KJV). That is where we belong. Their habits may be offensive to us, but that is understandable. We do not have to pronounce judgment on them; God will do that. We are to love them and understand that they do not have any basis of knowledge for a change. We are not to demand it of them before we begin to show friendship and love and reach out to them to help them to see their need, to see the One who can answer the hunger of their hearts. What we offer the world is the gospel, not condemnation but the good news.
