5 Walk in wisdom toward those who are outside, redeeming the time. 6 Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one. (Colossians 4:5–6, NKJV)
Wisdom is the application of known truth, at the right time and in the right measure. It is the use of spiritual discernment, in love and knowledge, to advance the excellent things of righteousness that glorify God and approve us in His sight (Philippians 1:9-11). When we flavor our words with graciousness we walk in wisdom by making the most of our opportunities toward the lost. Like food seasoned with salt, wisdom learns when and how to answer those who are outside of Christ (as well as fellow Christians) so that our opportunity to teach and persuade others is maximized. Put simply, we have an obligation to give gracious answers to others. Wisdom knows this, and helps us speak so as to enhance, not disrupt, our chance to communicate truth to others. Unless we season our words with grace we fail to redeem our opportunity to help someone follow Jesus.
