Parables of the Lamp and the Measure
 And He (Jesus) said to them, "Is a lamp brought in to be put under a bushel, or under a bed, and not on a stand?  For there is nothing hid, except to be made manifest; nor is anything secret, except to come to light.  If any man has ears to hear, let him hear."  And He said to them, "Take heed what you hear; the measure you give will be the measure you get, and still more will be given you.  For to him who has will more be given; and from him who has not, even what he has will be taken away."
21. A "bushel" was a container used for measuring cereals and vegetables. It held a little over eight liters (two gallons).
22. This parable contains a double teaching. Firstly, it says that Christ's doctrine should not be kept hidden; rather, it must be preached throughout the whole world. We find the same idea elsewhere in the Gospels: "what you hear whispered, proclaim it upon the house-tops" (Matthew 10:27); "Go into all the world and preach the Gospel to the whole of creation..." (Mark 16:15). The other teaching is that the Kingdom which Christ proclaims has such ability to penetrate all hearts that, at the end of time, when Jesus comes again, not a single human action, in favor or against Christ, will not become public and manifest.
24-25. Our Lord never gets tired of asking the Apostles, the seed which will produce the Church, to listen carefully to the teaching He is giving: they are receiving a treasure for which they will be held to account. "To him who has will more be given...": he who responds to grace will be given more grace and will yield more and more fruit; but he who does not will become more and more impoverished (cf. Matthew 25:14-30). Therefore, there is no limit to the development of the theological virtues: "If you say `Enough,' you are already dead" (St. Augustine, "Sermon 51"). A soul who wants to make progress in the interior life will pray along these lines: "Lord, may I have due measure in everything, except in Love" ([St] J. Escriva, "The Way", 247).
