The voice of John the Baptist crying out in the wilderness “Prepare the Way of the Lord!” is so familiar to long time people of faith that we sometimes think John is foretelling Christmas.
He is not.
John is a voice from the margins, somebody from the outside of power speaking to core abuses. He fulfills prophecy because God’s chosen generally find themselves in this position – that is, speaking from the outside in. The “coming” John proclaims is the adult Jesus, sent to usher in a new age. Today it is enough just to recognize that his is always what the Word of God is up to – the new.
