Before Novena prayer for Annuciation http://www.ewtn.com/Devotionals/Novena/annovena.htm
we can meditate faithfully over the great mystery of the moment of Incarnation of the Word of God , the most Holy and Immaculate Conception .
In the Feast of the Annunciation, the Church commemorates two events important to all humanity. On this day, the Archangel Gabriel appeared to Mary to announce that she was to be the Mother of of the Redeemer and Messiah promised for centuries in prophecy. On the same day, the Incarnation took place. God the Son, the second person of the Trinity, assumed a human body and soul and became the Son of Mary and Joseph.
The Incarnation proves that Mary is the Mother of God.
She is the Mother of the Divine Redeemer of the world, the Mother of our Lord and Master, our perfect friend and guide to her Son. After His heavenly Father and the Holy Spirit, there is no-one Jesus honours so much as His Blessed Mother. She intercedes for us to Her Son, and has been blessed with the privilege of appearing to us on occasion, as at Fatima and Lourdes.
The Feast of the Annunciation is an opportunity to bow our heads and thank Our Blessed Mother for her faith and trust, and to offer our own trusting 'Fiat' to God's designs.
