"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." Matthew 5:13. Jesus says this early in the Sermon on the Mount, before a single command has been given about prayer, giving, or the law. Before He tells His disciples what to do, He tells them what they already are. "Lost his savour" translates a single Greek verb, *moraino*. Its root is *moros* — the word from which we get "moron" — and its plain meaning is not "gone flat" or "lost flavor" but "become foolish." Jesus is not merely describing a chemical change in a seasoning; He is calling flavorless salt *foolish* salt, salt that has forgotten what it is for and no longer acts like itself. The image is almost comic and entirely serious at once: salt playing the fool. Paul uses this exact verb twice, and the pairing sharpens the point. In Romans 1:22 he writes of those who "professing themselves to be wise, they became fools" — *emoranthesan*, the same root. And in 1 Corinthians 1:20 he asks, "Hath not God made foolish the wisdom of this world?" — again, *emoranen*. Scripture uses this one word-family for the world's wisdom collapsing into folly before God, and for salt that has quit tasting like salt. The overlap is not incidental. A disciple who blends so fully into his surroundings that nothing distinct remains has undergone, in the Bible's own vocabulary, the same kind of foolishness Paul assigns to a civilization that traded the knowledge of God for idols. This reframes what it costs to lose your edge. The danger Jesus names is not merely uselessness — it is a reversal of identity so complete that the very thing called wise by the world (fitting in, dulling every sharp conviction until nothing chafes) is, in God's own words for it, foolish. Salt does not become foolish by trying too hard to be salty; it becomes foolish by quietly stopping. The warning is aimed at disciples already inside the kingdom, not at outsiders — the temptation is never abandoning the faith outright, but letting its distinct taste dissolve unnoticed into everything around it. Reflect: Where has your faith grown flavorless without your noticing — not abandoned, just dissolved into agreement with everything around you? What would it look like this week to taste, again, distinctly like yourself?

The Foolish Word Behind 'Lost His Savour'
The Greek verb behind 'lost his savour' in Matthew 5:13 — moraino, the root of our word 'moron' — means to become foolish, the very word Paul uses for human wisdom turned to folly.
Frequently asked questions
What does "lost his savour" mean in Matthew 5:13?
The Greek verb is moraino, meaning "to become foolish" (the root of the English word "moron"), not simply "lost flavor." Jesus describes salt that no longer acts like salt as salt that has become foolish, forgetting its own purpose.
Is the Greek word for "lost his savour" used anywhere else in the New Testament?
Yes. Paul uses the same verb in Romans 1:22 ("professing themselves to be wise, they became fools") and 1 Corinthians 1:20 ("Hath not God made foolish the wisdom of this world?"). The same word describes human wisdom collapsing into folly and salt that has quit tasting like salt.
What is the practical meaning of "salt that has lost its savour" for believers?
It warns disciples already inside the kingdom against losing their distinctiveness by blending unnoticed into their surroundings, not against outright abandoning the faith. In the Bible's own vocabulary, that quiet dissolving of conviction is itself a form of foolishness.
