On the next day, the multitude that stood on the other side of the sea saw that there was no other boat there, except the one in which his disciples had embarked, and that Jesus hadn't entered with his disciples into the boat, but his disciples had gone away alone.

 That is why Jesus can satisfy the eternal hunger. He is sealed by God, he is God's truth incarnate and it is God alone who can truly satisfy the hunger of the soul which he created.
