The Readings for this day highlight the words: Here I am Lord, I come to thy will. Mary re-echoes the theme when she Be it done unto me according to your word. We all have our moment of annunciation and are called to lay our lives open to God, that his will,-- his creative word may take flesh in us.
In meditation little else is asked of us, but that we sit in God's presence and let the river of his life and love flow through us. Here I am Lord, I come that your wonderful will may wash me clean and give me a new heart, a new purpose.
