No man, when he hath lighted a candle, covereth it with a vessel, or putteth it under a bed; but setteth it on a candlestick, that they which enter in may see the light. The meaning of the Lord's saying here is—the disciples must not look on this parable-method of teaching, which from henceforth he purposed frequently to adopt, as mysterious, or as containing anything beyond ordinary human comprehension.
The explanation of "the sower," which he had just given them, showed them how really simple and adapted to everyday life his teaching was. "No man," said the Lord, "when he hath lighted the candle of the true knowledge, really wishes to hide it—he rather displays it that men may see the light; and that is what I have been doing for you in my careful explanation of my story."
