Craig Williams has authored a thoughtful piece on his blog which he calls 'Advent Morality.' It deals with the implications for our lives of Mary's song in the Gospel of Luke's account of Jesus' birth and what exactly God's will is for our lives. Craig avoids what have become Christian cliches and instead upholds what God tells us about His will through the Christ Child. Bravo, Craig!
Also, take a look at my message on Mary, here.
