Luther says –
Christ gives us another lesson in faith, that we should not be overanxious about our daily bread and our temporal existence, and stirs us up by means of a miracle; as though to say by his act what he says by his words in Matthew 6,33: “Seek ye first the Kingdom of God, and his righteousness, and all these things shall be added unto you.” For here we see, since the people followed Christ for the sake of God’s Word and the signs, and thus sought the Kingdom of God, he did not forsake them but richly fed them. He hereby also shows that, rather than those who seek the Kingdom of God should suffer need, the grass in the desert would become wheat, or a crumb of bread would be turned into a thousand loaves; or a morsel of bread would feed as many people and just as satisfactorily as a thousand loaves; in order that the words in Matthew 4,4 might stand firm, that “Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.” And to confirm these words Christ is the first to be concerned about the people, as to what they should eat, and asks Philip, before they complain or ask him; so that we may indeed let him care for us, remembering that he cares more and sooner for us than we do for ourselves.
He cares for us sooner and more than we care for ourselves. Would that we would learn that lesson.
