How do we know God's grace is reflected in Mary, the mother of Jesus?

Mary, the mother of Jesus, embodies the concept of 'grace upon grace' as she is referred to as 'highly favored' by God. This grace signifies not only her blessed role as the mother of Jesus but also highlights the profound humility she exhibited in accepting God's will. The angel's proclamation emphasizes her unique position in salvation history, being chosen to bear the Messiah without claiming divine status for herself. Her response represents the truth that all believers experience a measure of grace akin to hers, showing that God's favor is granted out of His love and not based on personal merit or works.
