How does Mary's song relate to God's grace?

Mary's song, particularly in Luke 1:48-50, highlights the theme of God's grace as she reflects on her lowly status and how God has regarded her with favor. She acknowledges that His mercy extends to those who fear Him from generation to generation. This encapsulates the essence of sovereign grace – that God, in His mercy, chooses to lift those who are humble and contrite. Mary's recognition of her need for a Savior underscores the biblical truth that all believers, like her, are recipients of God's unmerited grace, illustrating salvation's origins solely in God's willingness to save the undeserving.
