I think that we, just like the disciples, try to find our fill with bread that will not sustain us. We live for the “big experiences” in our faith – the mission trips, the conversion experiences, the prayers with first time believers and the miracles that we see in our daily lives.
Jesus—God in human flesh—knows our hungering, both physical, and spiritual. Jesus knows that we need bread to provide us sustenance: the Bread of the Presence, Our Daily Bread, the Bread from Heaven.
Jesus does so much more than saying he is the Bread of Life. He fulfills his promise as he and his disciples share the Last Supper and he proves it through his sacrifice on the cross.
