Mark 8:1-30 parallels Mark 6:30-7:37. Feeding a great multitude; boat trip; confrontation with the Pharisees; conversation about bread; miraculous healing; significant confession (that we will get into in 2 weeks). I think Mark presents things in this order for 2 reasons. One is obvious: because that’s how it happened. Second is for discipleship. Remembering what God has done in the past should help us trust him with our present and future. Unfortunately we are sometimes hard hearted, blind, and deaf just like the disciples.
