“If your brother sins, go and show him his fault in private; if he listens to you, you have won your brother. But if he does not listen to you, take one or two more with you, so that by the mouth of two or three witnesses every fact may be confirmed.”
“If he refuses to listen to them, tell the church; and if he refuses to listen even to the church, let him be to you a Gentile and a tax collector.”
Matthew 18:15-17
Jesus was a master of managing human relations. He spoke about the fellowship of the church being disrupted and damaged by those who continued to sin. Jesus calls us to speak privately with someone regarding their sinful behavior and failing that to have others in the church join in helping the offender bring his/her lifestyle into line with the teachings of the scripture.
Jesus also acknowledged that this can fail spectacularly. And, even sometimes result in having to ask a person to leave the church. It is not an easy thing to do, but sometimes it must be done to preserve the fellowship and integrity of the Church.
So, when we are called to do the hard stuff, we may not enjoy the process but we can take comfort in knowing we did the right thing.
