"Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer everyone."
Salt is an interesting choice of words here, isn't it? Salt gives flavor to a dish of food. It actually enhances the flavor that's inherent to the aforementioned food, rather than imposing it's own flavor. Also, salt was used in the OT for covenant-making. The details aren't clear, but it was part of a binding agreement between two parties. Maybe Paul is reminding us that gracious speech binds our relationships?
Just about everyone talks. Just about everyone uses words. So everyone has a choice about what words they use. Sure, it may require a bit of self-discipline, but we have the capacity to use "gracious speech." How awesome would this world be if everyone did just that?
