The sermon examines the Epistle of Jude, focusing on the identity of the author as a servant of Jesus and the specific audience addressed: those sanctified by God the Father, preserved in Jesus Christ, and called by His purpose. It explores the theological depth of sanctification through the work of the Trinity and the Word of God, emphasizing that believers are securely kept by the Father and the Son for eternal life. The message contrasts this secure preservation with the danger of false teachers who pervert grace into licentiousness, urging believers to earnestly contend for the faith once delivered to the saints. The tone is instructional and pastoral, encouraging the congregation to grow in the knowledge of God and to multiply in mercy, peace, and love as they reflect the praises of Him who called them out of darkness into His marvelous light.
