The phrase salty language in our time has reference to crude or angry speech. Since sailors have a reputation for such — cussing like a sailor. The salt in the ocean gives us the image from which the phrase has its origin.
In scripture there is also a reference to salty language or speech, but it is a positive one. For example, in Colossians 2:5-6 Paul exhorted, “Walk in wisdom toward those who are outside, redeeming the time. Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one.” In Paul’s reference the speech that should be characteristic of the child of God is that which is gracious and wise, seasoned with truth and a beneficial relevance to those who hear.
As with all things Christian, it is speech that emanates from a place of love. As the Lord’s people, our desire and action should be to improve mankind. Things like anger, malice, profanity, innuendo, bitterness, lying, gossip, slander etc., do nothing for others, and so should be absent from our conversation!
“But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. Do not lie to one another, since you have put off the old man with his deeds, and have put on the new man who is renewed in knowledge according to the image of Him who created him” (Colossians 3:8-10).
