The sermon centers on the divine significance of Jesus' name, emphasizing that He was named Jesus by God the Father because He would save His people from their sins—a purpose rooted in divine sovereignty and fulfilled through Christ's incarnation, life, death, and resurrection. Drawing from Matthew 1:21 and Old Testament prophecy, it highlights that Jesus' name reveals His redemptive mission, linking Him to the figure of Joshua and the promise of a true, eternal promised land. The sermon underscores the certainty of salvation, asserting that Christ's work is complete and irreversible, as He will lose none of those given to Him, and His name—Jesus, meaning 'Yahweh saves'—is eternally secure. It calls believers to respond with worship, assurance, and reverence, warning against the blasphemy of misusing His name, while affirming that one day every knee will bow and every tongue confess Jesus as Lord, though for some it will be too late. Ultimately, the name of Jesus is the foundation of hope, salvation, and eternal joy.
