Intervention is necessary when our way of thinking, our desires, our thoughts about right and wrong come in direct contradiction with God’s will as witnessed and proclaimed in the life, ministry, teaching, death, and resurrection of Jesus.
Too often we play a guessing game with Christ’s identity, in which we force our perceptions and our desires of a Messiah upon Christ. But Christ didn’t come just for you, Christ came for all people, so stop claiming an infallible opinion of the Messiah, or you’ll be rebuked, just like Peter.
The disciples are given a purpose, they are given a mission, but Christ tells them to wait, for they do not yet have the power from on high. Sometimes waiting is a necessary thing.
