Luke 14:34 - Ellicott's Commentary On The Whole Bible

Salt is good. — The words are all but identical with those of Matthew 5:13, and resemble those of Mark 9:50. (See Notes on those passages.) They appear now, however, in a very different context, and the train of thought is not at first sight so clear. The common element in all three instances is that salt represents the purifying element in life, the principle of unselfish devotion. Here, the special aspect of that element is self-renunciation. In proportion as that is incomplete, the salt loses its savour. The question, Wherewith shall it be salted? is asked as in the accents of almost hopeless sadness. What other purifying influences can be brought to bear on us when the love of Christ has failed?
