Christmas is not merely a seasonal celebration but the climactic revelation of the Gospel—the good news that God, in eternal Sonship, became incarnate as a descendant of David to redeem humanity from sin and death. This divine act, foretold through the prophets, was not a departure from God's nature but the fulfillment of His eternal plan: the eternal Son, who is fully God, voluntarily emptied Himself, lived as a man, and died as a substitute for sinners, bearing the infinite penalty that finite humanity could not pay. His resurrection from the dead was not a mere miracle but the divine appointment that exalted Him as the powerful Son of God, confirming His victory over sin and death and establishing Him as the rightful Lord of all creation. As both God and man, Jesus now reigns at the Father's right hand, uniting humanity with divinity and securing eternal life for all who believe, making Christmas the foundation of hope, reconciliation, and ultimate restoration. The Gospel, therefore, is not a sentimental story but a cosmic event in which God Himself became flesh to save His people, and every knee will one day bow to the name of Jesus, the man who is Lord.
