The actual account of the Annunciation can be found in the Bible, in the first chapter of Luke's gospel. It begins with the angelic salutation of Gabriel to Mary: "Hail, thou who art highly favored; the Lord is with thee," and Mary's response to God's will, "Let it be done to me according to thy word."
What better proof of God's love for us that He chose to take on our humanity. He chose to become one of us as a tiny human baby developing and growing for nine months till His birth, which we celebrate on December 25. What better proof of God's love for us that He became "like us in all things except sin" at the moment of His conception in Mary's womb. What better proof of Mary's faith in God and love for us when she said, "Yes!" Mary said yes to God's plan because she wanted what God wanted through all the joy, through all the pain.
