John the Baptizer exhorts us to conversion. No one better than Mary can tell us what this conversion entails.
Conversion means turning away from yourself and turning to God instead. So, conversion is beginning to live as Mary did. She is so overwhelmed by the life growing in her body that she is not at all concerned about her own. Her center is not in herself, but in the life she is to give birth for the salvation of the world.
If you live along with Mary, turned away from yourself and turned toward God, then even you will give life to the world. You get to give birth to Christ. He has himself said: “Whoever does the will of my Father in heaven is my brother and sister and mother” (Mt 12:50).
If Christmas were only a celebration of an unusual child born two thousand years ago, then we wouldn’t need a long season of Advent to prepare for it. But Jesus is born within you, and preparation for this birth must be made.
John of the Cross writes in a small poem:
The Virgin with God’s Word
Carried in her womb
Comes toward you
If only you had room.
If you prepare a room for God, God will become real in you as he was in Mary.
