I once heard a speaker talking about those who only want to hear smooth things being spoken to them in correlation to us being the salt of the earth.. The point made was that while many want sweet (or smooth) things spoken to them, what they usually do with the salt when they want something sweet? They spit it out.
That this is a rebellious people, lying children, children that will not hear the law of the LORD: (10) Which say to the seers, See not; and to the prophets, Prophesy not unto us right things, speak unto us smooth things, prophesy deceits: (11) Get you out of the way, turn aside out of the path, cause the Holy One of Israel to cease from before us.
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. (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.
We are called to be the light of the earth. I’d say it’s time we start striving for that.
