Salt is good If you are not my disciples indeed, your outward profession will be very insignificant: for, though salt in general is a good thing, and my servants, as I formerly intimated (see on Matthew 5:13,) are the salt of the earth; yet I must again add, if the salt have lost his savour Or be grown insipid, how can its saltness be restored to it? or what can recover those whom my gospel will not influence and reclaim? It is neither fit for the land, &c. As insipid salt is such a vile and worthless thing, that it is neither fit to be used of itself, as manure for the land, nor even to be cast upon the dunghill, to be there mixed with other manure; but men cast it out It is thrown out of doors, and trampled under foot like mire in the streets. So you, my disciples, will be no less useless and contemptible, if, under the advantages and obligations of a Christian profession, you are destitute of a true principle of integrity and piety, of which you will certainly be destitute if you do not thus deny yourselves, and stand disposed to forsake all for my sake and the gospel's, as far as, and whenever, I shall call you to it. See notes on Mark 9:49-50.
