In his response to the request of the mother of the sons of Zebedee for places on the right and left of Jesus, Jesus takes the disciples to another level and perspective of leadership where to be a leader is not to dominate or dictate but to serve. Christian leadership may be defined as service.
James understood this after the death and resurrection of Jesus as was evident in his martyrdom. He followed his Lord and Master to the end and did indeed drink the cup courageously.
Will you like St. James drink your cup of suffering courageously?
