The sermon centers on the declaration that Jesus is both Lord and Christ, emphasizing this as the core of the gospel message. Drawing from Peter's Pentecostal sermon and examining the life, death, and resurrection of Christ, the message asserts that these events definitively establish Jesus' dual role as both divine authority and the promised Messiah. The preacher challenges listeners to confront this truth, acknowledging that claiming Jesus as Lord requires submission to His authority and a recognition of His supremacy over all creation, while also highlighting the historical context of Jewish and Roman rejection of this claim and calling for a personal commitment to acknowledging Jesus as Lord and Savior.
