Mary received a promise from an angel that she would conceive and give birth to Jesus, who would be great and reign forever. While the promise sounded wonderful, Mary's experience did not unfold as expected, with Jesus being misunderstood and crucified. Mary maintained her faith through it all by repeating her commitment to God's will. The document encourages embracing God's promises through faith even when life does not go as planned, as God's love and promises never fail.
