In Mark 6 after the disciples get back from their short-term mission trip, Jesus demonstrates His power by feeding 5,000 men with 5 loaves and 2 fish and then walking on water before healing people simply through being touched by them. In the midst of these demonstrations of His power though he is teaching us something about the nature of discipleship and His invitation to all of us to be disciples, to spend time with Him and to be empowered by him to reach the world.
