John 6 is one of my favorite chapters in John. Here is where Jesus reveals the true nature of belief and brings the crowds to a crossroads.
Jesus’ popularity is soaring. People are literally running from town to town to catch up with him. They have heard of the miraculous healings and have been told that if they just touch the fringe of his garment they will be healed. Even King Herod is seeking an audience with him.
Following the feeding of the five thousand, the crowds go searching for him but instead of soaking up all the attention he confronts them by revealing their true motives in searching for him. They’re only seeking a full stomach, not a satisfied soul.
Jesus was willing to offend the crowds and risk losing that popularity. He does this to winnow the crowd, to reveal those who are truly believers.
Jesus knows the plan of the Father. His Father sent him to execute it. He does not put any confidence in man for he knows what is in man. His confidence is in the perfect union he has with his Father and that the Father knows those who belong to him. No one can come to him unless the Father draws him. (John 6:61-65)
