Colossians 4:6

Let your speech be alway with grace,— "Always conducted in the most mild and courteous, the most proper and graceful manner; so that it may appear influenced by a governing principle of divine grace and unfeigned piety in your hearts. Let it in this respect be so seasoned with the salt of heavenly wisdom as may render it savoury and edifying. In thisview reflect upon things and circumstances before you speak, that you may not utter any thing which would be rash and foolish, but may know how you ought to answer every one who may question you about your religion and your conduct, in such a manner as may most effectually and jointly tend to your own security and that of your brethren, and the edification of others." See 1 Peter 3:15.
