The sermon traces the fulfillment of Old Testament prophecy in the birth of Jesus Christ, emphasizing God's faithfulness across centuries. Beginning with Isaiah's prophecy of a virgin conceiving and bearing a son named Immanuel—God with us—the message underscores the miraculous, divinely orchestrated nature of Christ's incarnation, which defied human logic and was foretold over 700 years in advance. The narrative then unfolds through the lives of Zechariah and Elizabeth, whose son John the Baptist would prepare the way for the Messiah, and Mary, who humbly submitted to God's plan despite her confusion, becoming the vessel through whom the Son of God entered history. The sermon highlights how every detail—from the virgin birth and divine conception by the Holy Spirit to the fulfillment of covenant promises in David's line—demonstrates God's sovereign grace and the impossibility of human achievement, culminating in the declaration that Jesus, the Savior, would redeem His people from their sins. This historical and theological foundation is not merely a past event but the living reality of God's ongoing work, pointing forward to Christ's resurrection, ascension, and promised return, where His victory over sin and death continues to transform lives.
