More thoughts...
Have just been thinking about wilderness, largely because I read this Jesus' story ( as told by Matthew) begins with the genealogy, but also with the wilderness. jesus' ministry starts with 'you are my beloved son' but then Jesus is sent to the wilderness. Even creation itself starts with wilderness and then the naming of humanity. Is there something about the desert, the bleak place, the emptiness that helps us to take in what this sense of being one of God's own people really means?
