The angel Gabriel announces to Mary that she is to be the Mother of God.
When the angel entered Mary's dwelling, he found her surrounded by the fragrance of silence. The Lord of all creation waited for the word of His creature, and Heaven stood still before her "Fiat." Humility became the throne of Omnipotence. Mary's lowliness was not ignorance of her grace, but clear vision of her nothingness beside Infinite Majesty. In her, self-love was extinguished, and divine light had free passage.
So too must the soul bow low if God is to dwell within it. He will not descend into hearts filled with the noise of their own importance. The humble soul is a vessel empty enough to receive the ocean. When we say with Mary, "Be it done," we allow God to shape in us what we cannot fashion for ourselves. Thus humility is not weakness, but the silent might that lets God be all.
