Baptized by John the Baptist, filled with the Holy Spirit: to preach the kingdom of God to the poor, to heal the sick, to receive those who have been cast out, to revive Israel for the salvation of the nations, and to have mercy upon all people.
Without something like this, nothing in the life of Jesus registers, and he goes right from birth to death - no teachings, no miracles, no example for living. A purely transactional incarnation!
