On occasion a Christian will wander away from the fellowship of other believers and find himself ensnared by sin through ignorance or willful disobedience. It then becomes necessary for the church, and particularly its shepherds, to actively seek the repentance and restoration of that Christian. As shepherds of the flock, the elders love the sheep and are also held accountable by God for their spiritual welfare, including that of the wandering sheep. As in Jesus' parable in Luke 15:3-8, it is a time of joy, both in heaven and within the church, when the wandering Christian truly repents. One means by which the church seeks to lovingly restore wandering believers is the process of church discipline. In Matthew 18, the Lord explains to His disciples how to respond when a fellow believer sins. The principles He sets forth must guide the body of Christ as she seeks to implement discipline in the church today.
