Colossians 4:6 Updated American Standard Version (UASV)
6 Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person.

“For the sharing of the message of Christ to be effective, the wise walk must be accompanied with flavorful talk. The believer’s talk is to be gracious, rather than gruff, and charming, rather than coarse. … The believer’s speech is to be free from corruption, wholesome. The believer’s speech is to be interesting, witty, tactful, and appealing. The believer’s speech is to be both wholesome and appealing. Paul wants believers to know how to answer everyone. He tells them to answer with speech which is gracious, wholesome, and appealing.” Max Anders.
