The angel Gabriel was sent from God to a town of Galilee called Nazareth. And coming to Mary, he said, "Hail, favored one! The Lord is with you." (Lk 1:26-28) ...
The time for the Incarnation is at hand.
Of all women God prepared Mary from her conception to be the Mother of God.
The Angel Gabriel announces: "Hail, full of grace! The Lord is with thee."
Mary wonders at this salutation.
The Angel said: "Fear not - you shall conceive in your womb, and give birth to a Son."
Mary is troubled for she has made a vow of virginity.
The Angel: You will conceive by the power of the Holy Spirit, and her Son will be the Son of God.
The Incarnation awaits Mary's consent.
Mary answers: "Behold the handmaid of the Lord. Be it done unto me according to yourword."
