Scripture calls every believer to continual self-examination so that hidden sin is confessed, fellowship with God is renewed, and spiritual growth continues. God provides multiple “mirrors” for this process—the Lord’s Supper, life’s trials, the inner witness of the Holy Spirit, caring leaders, and even corrective suffering. When we neglect these graces, He lovingly chastens us so we may share His holiness and become overcomers who reflect Christ to the world.
