until you've multiplied the current phase
expense goes up with each larger phase

largest influence in smaller units, most demands in larger units
What was the role of Jesus in each phase?
Jesus was a discipler
Jesus was a brother
Jesus was an equipper
Jesus was a shepherd
Jesus was a visionary
Jesus was a teacher/healer
