The sermon unfolds the redemptive arc of Scripture by highlighting three pivotal moments in Old Testament history—Abraham, David, and exile—as divine milestones leading to Christ's advent. It emphasizes that while Abraham's covenant initiated God's promise of a nation and blessing, and David's reign symbolized the pinnacle of earthly kingship, both were ultimately insufficient, pointing to a greater fulfillment yet to come. The exile, though a time of profound despair and divine judgment due to national unfaithfulness, becomes the necessary context for God's promise of a new covenant—unlike the broken Sinai covenant—where His law is written on hearts, sins are forgiven, and all will know Him personally. This new covenant, fulfilled in Christ, is not a renewal but a qualitative transformation, establishing an eternal, unbreakable relationship grounded in grace rather than law, making Advent not merely a nostalgic celebration but a joyful recognition of God's sovereign victory over sin, death, and human failure through the incarnate Son.
