This sermon centers on the profound truth that sacrificial love, exemplified most fully in God's gift of His Son, is the heart of Christmas and the foundation of Christian faith. Drawing from Genesis 22's account of Abraham's willingness to sacrifice Isaac—foreshadowing God's ultimate provision of Jesus—the message unfolds through biblical narratives of Moses, Esther, and Jesus' own self-giving love, illustrating how true love involves obedience, costly surrender, and divine provision. The preacher emphasizes that love is not sentimental but sacrificial, demonstrated in Christ's incarnation, crucifixion, and resurrection, which reconcile humanity to God and offer eternal life to all who repent and believe. The sermon calls listeners to recognize their need for salvation, embrace the free gift of grace, and live in the joy, hope, and transformative love that flows from Christ's victory over sin and death.
