A few generations ago, when someone in the church membership was known to be living a lifestyle of sin and that fact was affirmed by two or three witnesses, that person was first warned and counseled by the leaders of the church. If he/she refused to change their ways, they were brought before the congregation for disciplining. When they were found guilty and refused to repent, they were asked to leave the church. It is not only scriptural for us to do that but it is our responsibility to do it. First, we must make sure that there is no yeast in ourselves and then we can judge those of the household of faith. It is not our responsibility or business to judge non-Christians, that is God’s business and He will take care of it in His own time. A church body with sin in it is a weak body and it will not attract unbelievers to Christ. In fact, outsiders will turn away from that body because of the hypocrisy. We, as church bodies, don’t do this much anymore. I believe that is one of the biggest reasons for the decline in church memberships and that fewer people attend church. Let us be sure that we are not living a lifestyle of sin ourselves and then make sure that any yeast or leaven is removed from the church body. No one wants to be around a body that is going through the process of putrefaction. We need to clean it up and shine for our Lord and Savior, that light will attract others to Christ.
