St. Thomas Aquinas, based on Mark 4:21-25
He said to them, “Is a lamp brought in to be put under the bushel basket, or under the bed, and not on the lampstand? For there is nothing hidden, except to be disclosed; nor is anything secret, except to come to light. Let anyone with ears to hear listen!” And he said to them, “Pay attention to what you hear; the measure you give will be the measure you get, and still more will be given you. For to those who have, more will be given; and from those who have nothing, even what they have will be taken away.”
