Matteo 5:13

The Chief Functions of the Disciples in the World.

The Lord continues to address His disciples directly: Ye are the salt of the earth; but if the salt have lost his savor, wherewith shall it be salted? It is thenceforth good for nothing but to be cast out and to be trodden under foot of men.

Having experienced the sanctifying power of the Word and Spirit of Jesus, the disciples are a salt. Note the four main qualities of salt: It is white and pure, it prevents rapid decay, it preserves nutriment and flavor, it renders the food palatable and healthy. The Christians are the salt of the earth; their business is to prevent its decay and putrefaction, to use every effort that the moral rottenness of the children of the world does not become excessive and render every class and age of society putrid by its infection, 1 Corinthians 15:33.

This is not an easy task. But "our defiance, when things go badly, and when the world and the devil give us evil looks, and are as angry as they wish, is this, that He says to us: Ye are the salt of the earth. Where this word shines into the heart that it puts its trust in that and glories without doubting that we are God's salt, then let everyone be thoroughly angry that will not laugh. I can and may put more defiance and boasting upon a single word of His than they upon their might, swords, and guns.

" If this salt now loses its flavor, it becomes insipid. This is true only of salt that undergoes a chemical process, either by being exposed to rain or by being stored for some length of time, as travelers from the Holy Land report. The figure of Christ is thus particularly apt. Insipid, saltless salt is really a contradiction in itself, and Christians that have lost their distinctive properties have ceased to influence their surroundings for good, have also lost their discipleship.

As savorless salt has no value whatever and is treated as refuse; as a certain species of bituminous salt found in Judea which very rapidly became flat and tasteless was spread out in a court of the Temple to prevent slipping in wet weather, so the Christians that have ceased to apply themselves to their business of acting as a moral power in the world, will partake of the judgment of the world. Luther probably is right in saying: "Therefore I have always admonished, as Christ also does here, that salt remain salt and not become insipid, that is, that the chief article of faith be urged. For if that ceases, then not one piece can remain, and everything is lost; there is neither faith nor understanding, and no one can teach or counsel properly anymore."
