Jesus insists that he is the true bread from heaven; he is the real basis of our survival. If we fill ourselves with all that the world provides as nourishment we will still hunger. Only faith in Jesus can satisfy our deepest hungers, and we will not be able to survive apart from him. Acceptance of Jesus as the source of our life and the very nourishment of our spirits effects a total transformation in us. We will no longer be content to live with full bellies but empty minds. We will put aside our old selves steeped in ignorance and self-interest and put on a new self, created in his image. Having fed on the bread from heaven, we will be mysteriously transformed into it. The spirit of our minds will be renewed by his teaching. As a result, we will be able to launch out into a way of living that witnesses to our new understanding, our new life.
