Two specific powers are defined in Matthew. 1) Casting out spirits, and 2) Healing the sick. First on Matthew’s list is the need to be aware that the enemy has taken territory “inside people” in physical, psychological, and emotional capacities. The mission of the Disciples was to bring FREEDOM to people from this. That is mercy. The second purpose is to bring healing to the sick. This sickness leans more toward the results of sin entering the earth. That is grace.

Another amazing truth is that Jesus tells His disciples to pack light. That's right, contrary to excessive planning. There must be an element of faith combined with our willingness to enter into ministry. We don't enter in when everything's perfect.
