Matthew 5:13

“Ye are the salt of the earth, etc.] This is to be understood of the disciples and apostles of Christ; who might be compared to “salt”, because of the savoury doctrines they preached; as all such are, which are agreeable to the Scriptures, and are of the evangelic kind, which are full of Christ, serve to exalt him, and to magnify the grace of God; and are suitable to the experiences of the saints, and are according to godliness, and tend to promote it: also because of their savoury lives and conversations; whereby they recommended, and gave sanction to the doctrines they preached, were examples to the saints, and checks upon wicked men. These were the salt “of the earth”; that is, of the…”

“We have here the practical application of the foregoing principles to those disciples who sat listening to them, and to their successors in all time.

It enters into the very nature of the substance. In eastern…”

“Ye - Not the apostles, not ministers only; but all ye who are thus holy, are the salt of the earth - Are to season others. Mar 9:50; Luk 14:34. Matthew 5:14”

“5:13-16 The disciples’ good deeds will have profoundly positive effects on the world around them, to the glory of God. With this comes a warning from Jesus: Do nothing that might jeopardize that positive influence. 5:13 Salt was used for cleansing and preservation from decay (Ezek 16:4), in forming covenants (Lev 2:13; Num 18:19; see study note on 2 Chr 13:5), and as flavor (Job 6:6; Mark 9:50). • Salt that lost its flavor became useless, insipid, or dull (see Mark 9:50; Luke 14:34).”
