That's some fire. St. Mark begins his Gospel, his way of telling the story of the Son of God, with words of baptism in dirty water and the fire of Jesus' Spirit. We are river water people, called to stir things up. And his life showed it. Prepare the Way of the Lord.
Life can be a wilderness, with murkiness clouding our vision.
We cannot save ourselves. We need water and fire if this life, and the life to come, is to bring us joy. In order to know this joy, we simply open our hearts, and let God have his way with us.
