This sermon centers on the profound truth that Jesus, the promised Messiah, is God with us—fully divine and fully human, sent to save His people from their sins. Through the narratives of Mary, Joseph, and Christ, it emphasizes that God chooses ordinary individuals—Mary, a humble young woman, and Joseph, a righteous man of quiet faith—not for their merit, but for His grace and sovereign purpose. The sermon underscores the necessity of the virgin birth as foundational to Christ's sinless nature and redemptive mission, while affirming that Jesus' name—meaning 'the Lord saves'—reveals His divine mission: to justify, sanctify, and ultimately glorify His people. It calls believers to respond with humble faith, obedient trust, and a life centered on Christ, who fulfills God's promises and completes salvation through His finished work on the cross, ensuring that no one who belongs to Him will be lost.
