The Lord's love knows no bounds, but man can put a limit on it.
"You are clean, but not all of you" (Jn 13: 10): What is it that makes man unclean?
It is the rejection of love, not wanting to be loved, not loving. It is pride that believes it has no need of any purification, that is closed to God's saving goodness. It is pride that does not want to admit or recognize that we are in need of purification. ...
"You are clean, but not all of you". Today, the Lord alerts us to the self-sufficiency that puts a limit on his unlimited love. He invites us to imitate his humility, to entrust ourselves to it, to let ourselves be "infected" by it.
He invites us - however lost we may feel - to return home, to let his purifying goodness uplift us and enable us to sit at table with him, with God himself.
