Matthew 5:13-14

Verse 13. Ye are the salt of the earth. Salt renders food pleasant and palatable, and preserves from putrefaction. So Christians, by their lives and instructions, are to keep the world from entire moral corruption. By bringing down, by their prayers, the blessing of God, and by their influence and example, they save the world from universal vice and crime.

Salt have lost his savour. That is, if it has become insipid, tasteless, or have lost its preserving properties. The salt used in this country is a chemical compound--muriate of soda-- and if the saltness were lost, or it were to lose its savour, there would be nothing remaining. It enters into the very nature of the substance. In eastern countries, however, the salt used was impure, mingled with vegetable and earthy substances; so that it might lose the whole of its saltness, and a considerable quantity of earthy matter remain. This was good for nothing, except that it was used, as it is said, to place in paths, or walks, as we use gravel. This kind of salt is common still in that country. It is found in the earth in veins or layers, and when exposed to the sun and rain, loses its saltness entirely. Maundrell says, "I broke a piece of it, of which that part that was exposed

to the rain, sun, and air, though it had the sparks and

particles of salt, yet it had perfectly lost its savour.

The inner part, which was connected to the rock, retained

its savour, as I found by proof."

Verse 14. The light of the world. The light of the world often denotes the sun, Jn 11:9. The sun renders objects visible, shows their form their nature, their beauties, and deformities. The term light is often applied to religious teachers. See Jn 1:4, 8:12, Is 49:6. It is pre-eminently applied to Jesus in these places; because he is, in the moral world, what the sun is in the natural world. The apostles, and Christian ministers, and all Christians, are lights of the world, because they, by their instructions and examples, show what God requires, what is the condition of man, what is the way of duty, peace, and happiness--the way that leads to heaven.

A city that is set on an hill, etc. Many of the cities of Judea were placed on the summits or sides of mountains, and could be seen from afar. This was the case with Jerusalem; and it is said by Maundrell, that near the place where our Saviour is supposed to have delivered his sermon, there is still such a town, called Saphat, anciently This can Bethesda. be seen far and near. Perhaps Jesus pointed to such a city, and told his disciples that they were like it. They were seen from far. Their actions could not be hid. The eyes of the World were upon them. They must be seen; and as this was the case, they ought to be holy, harmless, and undefiled.
