How does Mary's story reflect the doctrine of grace?

Mary's story epitomizes grace as it showcases how God chose her not for her holiness but because of His favorable disposition towards her despite her lowly status. Ephesians 1:6 states that we are accepted in the Beloved, illustrating a parallel to Mary being highly favored. Mary's acceptance is a testament to God's grace; it emphasizes that all believers receive grace that is unmerited and transformative, reflecting the core doctrine that salvation comes solely through God's action, not human merit.
