5 Walk in wisdom toward outsiders, making the best use of the time. 6 Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person.
Speak to others from your own changed life. Speak in such a way that gives a flavor and preservation (salt effect) to your words. Speak in such a way that would cause others to ask questions about your faith. Speak that you would be able to answer questions about the gospel without reproach.
Don’t assume people are believers. Don’t expect others to live like believers in Christ until you know that they are genuinely believers in Christ. Don’t let your personal views (sports, politics, sororities, fraternities, etc…) come through before gospel-driven, Christ-exalting language comes through. Don’t waste time.
Remember this, your words mean something and the way you speak says just as much. Reflect on the above passage long enough for its simple exhortation to cause you to think twice (or even be convicted) about what you say toward outsiders and how you treat them.
