“Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.”
King James Version (KJV)
4:6 Let your speech be always with grace - Seasoned with the grace of God, as flesh is with salt.
Col 4:6 Let your speech [be] always with grace. Use courteous speech, calculated to attract rather than to repel. Seasoned with salt. Food without seasoning is insipid. Let the speech be so seasoned by "grace" that it will not be rejected with aversion. That ye may know how ye ought to answer every man. So that your answer to every man may be such as the case requires. The idea is to always say what is pertinent and best for the occasion.
