How do we know that Mary needed a Savior?

Mary's declaration in Luke 1:47 serves as clear evidence of her need for a Savior. She states, 'My spirit rejoices in God my Savior,' which shows that she recognized her own sinful state and the necessity of divine salvation. This challenges the notion that Mary was sinless; instead, it affirms that she, like all humanity, required a Savior. By acknowledging her need for salvation, Mary exemplifies true humility, recognizing the grace of God that was extended to her, and this mirrors the larger biblical narrative of redemption where all fall short of the glory of God and contribute to the need for Christ's saving work.
