Today is the Feast of Our Lady of Guadalupe. In the Gospel reading from Luke 1, the angle Gabriel came to Mary to announce the birth of Jesus to her. After she understood what God wanted to do with her, she said to the angel, "Behold, I am the handmaid of the Lord. May it be done to me according to your word." Indeed, it is the key to achieving union with God when you can say "May it be done to me according to your word" each time to the Lord.
