A Woman with Only Four "Words"

Earlier this week I was struck by our Blessed Mother's four "words" in Scripture: 

• "Be it done unto me according to Thy word"
• "My soul magnifies the Lord, and my spirit rejoices in God my Savior. . ."
• At Jesus' finding in the Temple, "Why have You done this to your father and me?"
• "Do whatever He tells you."

I want to explore those words more; it seems to me that the Blessed Mother managed to encapsulate the whole spectrum of our interior lives in those four words - Fiat, Magnificat, Why?, and Do.
