We must beware then of looking with repugnance on what Christ calls us to, as if it were a superfluity that may reasonably be postponed to more urgent and essential demands; or as if He were introducing our nature to some region for which it was not originally intended, and exciting within us spurious and fanciful desires which are really alien to us as human beings. This is a common thought. It is a common thought that religion is not an essential but a luxury. But in point of fact all that Christ calls us to, perfect reconcilement with God, devoted service of His will, purity of character,—these are the essentials for us, so that until we attain them we have not begun to live, but are merely nibbling at the very gate of life. God, in inviting us to these things, is not putting a strain on our nature it can never bear. He is proposing to impart new strength and joy to our nature. He is not summoning us to a joy that is too high for us, and that we can never rejoice in, but is recalling us to that condition in which alone we can live with comfort and health, and in which alone we can permanently delight. If we cannot now desire what Christ offers, if we have no appetite for it, if all that He speaks of seems uninviting and dreary, then this is symptomatic of a fatal loss of appetite on our part. But as Jesus would have felt a deeper compassion for any in that crowd who were too faint to eat, or as He would quickly have laid His healing hand on any diseased person who could not eat, so does He still more deeply compassionate all of us who would fain eat and drink with His people, and yet nauseate and turn from their delights as the sickly from the strong food of the healthy. 3. But what Jesus especially emphasises in the conversation arising out of the miracle is that the food He gives is Himself. He is the Bread of Life, the Living Bread. What is there in Christ which constitutes Him the Bread of Life? There is, first of all, that which He Himself constantly presses, that He is sent by the Father, that He comes out of heaven, bringing from the Father a new source of life into the world.
