This message centers on the fulfillment of Isaiah’s prophecy that a virgin would give birth to Immanuel, showing that Christmas celebrates God Himself coming to dwell with humanity through Jesus Christ. It emphasizes that the most important question anyone can answer is “Who do you say Jesus is?” and affirms, through Scripture, that Jesus is not merely a prophet or teacher but fully God—Immanuel, God with us. The sermon explains that Jesus is the cornerstone and only foundation of the Church and of every believer’s life, affirmed by the Father, the Holy Spirit, humanity, and Jesus Himself. It concludes by celebrating Christmas as the moment God entered human history, lived among us, died for our sins, rose again, and freely offers forgiveness, new life, adoption into God’s family, and eternal hope to all who believe.
