First, God feeds. He does not withhold food, except to the incorrigible (the damned) and, for a reason and a time, for the hard-hearted, for He draws them back through good discipline.
Second, God feeds in due season. It would not be “in season” for a person not in the state of grace to be fed. Hence, the Church’s constant and irrevocable Tradition of not granting those in the state of sin to receive the Holy Eucharist. When my child is sick, and vomiting up good food, I wait a while, offering just a very little drink (and one that goes down and stays down). This is to accompany the sick person. To feed the sick person the Eucharist would not be accompanying.
This little verse teaches us, gives us much to reflect on.
