14 Ye are the light of the world. A city that is set on an hill cannot be hid. 15 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. (Matthew 5:14-15 KJV)
Spurgeon’s Commentary on Matthew
14-15 We are to remove the darkness of ignorance, sin, and sorrow. Christ has lighted us that we may enlighten the world. It is not ours to lie in concealment as to our religion. God intends his grace to be as conspicuous as a city built on the mountain’s brow. To attempt to conceal his Spirit is as foolish as to put a lamp “under a bushel”: the lamp should be seen by “all that are in the house,” and so should the Christian’s graces. Household piety is the best of piety. If our light is not seen in the house, depend upon it we have none. Candles are meant for parlors and bedrooms. Let us not cover up the light of grace: indeed, we “cannot be hid” if once the Lord has built us on the hill of his love, neither can we dwell in darkness if God has lighted us, and set us “on a candlestick.” Lord, let me be zealous to spread abroad the light I have received from thee Even throughout the world! At least let me shine in my own.
