This sermon explores the true joy of Christmas as revealed in the gospel of Jesus Christ. Moving beyond emotional nostalgia, it highlights how Christmas joy flows from sacrificial giving—seen in Mary’s humble surrender, Joseph’s obedient faith, and supremely in God’s gift of His Son. The message explains the necessity of the incarnation, the meaning of Christ’s suffering, and why the cross stands at the center of Christian faith. True Christmas joy is found in sins forgiven, freedom from fear and death, and a restored relationship with God through Christ. This teaching calls believers to experience lasting joy through repentance, faith, and life in the Holy Spirit.
