Charles Spurgeon Commentary Matthew 5:15

"Neither do [men] light a lamp, and put it under the bushel, but on the stand; and it shineth unto all that are in the house." — Matthew 5:15 (ASV)

Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.

God's intent is, first, to light you; and, secondly, to put you in a conspicuous position, where men can see you.
