There are actually two kinds of bread: material -- helps us from without inwards; and spiritual -- helps us from within outwards. Jesus' concern was for the latter, because the inward life was, to him, the true life. As one commentator has written: "There is a vacuum in the soul of man which nothing can fill save faith in God." "He who believes in me shall never thirst" -- shall never be unsatisfied; shall never lack that chief ingregient needed to provide full life. Few of us take this seriously. If our physical condition is not up to par, we run to the physician. If we are frustrated, despondent, filled with a sense of failure, aimlessness, and lost meaning, we rarely get upset by it. We long for peace of mind, fulfillment, and a well--rounded life. We aspire, but fall short of spiritual awareness. This means: get to know him (read and reread the Gospels); live with him (talk to him in your prayers); love him (give him the edge of your affection over the things you crave for and want); and let his presence daily permeate your whole lifestyle. That is a tall order. It is a holy diet. It produces moving examples of eternal life.
