He exhorts: “Do not labor for the food which perishes, but for the food which endures to eternal life, which the Son of man will give to you” (v. 27). That is to say, seek salvation, the encounter with God.
With these words, he seeks to make us understand that, in addition to physical hunger man carries within him another hunger — all of us have this hunger — a more important hunger, which cannot be satisfied with ordinary food. It is a hunger for life, a hunger for eternity which He alone can satisfy, as he is “the bread of life” (v. 35). Jesus does not eliminate the concern and search for daily food. No, he does not remove the concern for all that can make life more progressive. But Jesus reminds us that the true meaning of our earthly existence lies at the end, in eternity, it lies in the encounter with Him, who is gift and giver. He also reminds us that human history with its suffering and joy must be seen in a horizon of eternity, that is, in that horizon of the definitive encounter with Him. And this encounter illuminates all the days of our life. If we think of this encounter, of this great gift, the small gifts of life, even the suffering, the worries will be illuminated by the hope of this encounter. “I am the bread of life; he who comes to me shall not hunger, and he who believes in me shall never thirst” (v. 35). This refers to the Eucharist, the greatest gift that satisfies the soul and the body. Meeting and welcoming within us Jesus, “Bread of Life”, gives meaning and hope to the often winding journey of life. This “Bread of Life” is given to us with a task, namely, that we in our turn satisfy the spiritual and material hunger of our brothers, proclaiming the Gospel the world over. With the witness of our brotherly and solidary attitude toward our neighbour, we render Christ and his love present amid mankind.
May the Blessed Virgin sustain us in the search and sequela of her Son Jesus, the true bread, the living bread which does not spoil, but which endures for eternal life.
[Pope Francis, Angelus 2 August 2015]
