This lesson explains the biblical process of church discipline from Matthew 18. It outlines five steps: personal self-discipline, private confrontation, involving one or two others, bringing the matter before the church, and, if there is continued unrepentance, removal from church membership. The lesson emphasizes that church discipline should always be handled with love, confidentiality, wisdom, humility, and patience. Its purpose is to encourage repentance, protect the purity of the church, and trust Christ to work through His people according to His Word.
