W. T. P. Wolston

The Lord now uses two striking figures to show what His own should be in His absence. "Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men. Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it gives light to all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven" (vers. 13-16). "Ye are the salt of the earth." Now salt is preservative, it preserves from corruption. When the saints are taken out of the earth there will be nothing left but the dead carcase of a Christless Christendom, nothing but corruption. Salt answers to righteousness. But "Ye are the light of the world," gives another thought. Light answers to grace. Salt merely preserves things pure from corruption, but light is aggressive, it drives out the darkness. So grace goes forth outside and seeks. "It gives light."
