Mary's song in Luke 1, a prophetic hymn of profound joy and theological depth, captures the culmination of God's redemptive plan from Eden to the new creation, celebrating the incarnation as the ultimate reversal of human pride and divine humility. Rooted in Old Testament themes of God's mercy, power, and faithfulness to Abraham and Israel, her praise reflects a deep familiarity with Scripture and a faith that embraces the miraculous without doubt, even amid personal humiliation and societal scorn. The sermon highlights how Mary's worship—marked by humility, submission, and joy—anticipates the gospel's core truths: God exalts the lowly, humbles the proud, and fulfills His promises through the divine-human Jesus, whose birth inaugurates a new creation. Through the lens of Spurgeon's joyful spirituality and the historical context of Mary's life, the message calls believers to emulate her faith, embrace the joy of Advent, and worship God in community, recognizing that the incarnation is the greatest act of divine mercy and holiness in history.
