When therefore they had rowed about twenty-five or thirty stadia,{25 to 30 stadia is about 5 to 6 kilometers or about 3 to 4 miles} they saw Jesus walking on the sea, and drawing near to the boat; and they were afraid.

 Jesus' point was that all that these Jews were interested in was physical satisfaction. They had received an unexpectedly free and lavish meal; and they wanted more. But there are other hungers which can be satisfied only by him. There is the hunger for truth--in him alone is the truth of God. There is the hunger for life--in him alone is life more abundant. There is the hunger for love--in him alone is the love that outlasts sin and death. Christ alone can satisfy the hunger of the human heart and soul.
