St. Mark has no Christmas. He begins the Gospel in the wilderness. In the beginning God created the heavens and the earth and it was good. But we thought we could live apart from every word that comes from the mouth of God (Lenten antiphon). And as a result this whole world became a wilderness.
Yet by God's grace, the wilderness is not as bad a place as it could be. In fact, He makes it to be a place of blessing - the place where God trains Moses, and Israel, and Elijah, and John the Baptist and his listeners to have no other gods, to learn to live again by every Word that comes from His mouth. We are in the wilderness, but Mark says Jesus is in the wilderness with us to save us.
