Colossians 4:6 Let your speech be always with grace, having been seasoned with salt, that you may know how you ought to answer each one.
Nowadays using salt is considered bad for our blood pressure, but in ancient times, salt was valued, traded. A seasoning of worth. Salt is a preservative, something to prevent food from spoiling in a time when refrigeration was not available. In ancient times, salt was a symbol of covenant. Treaties ratified with salt were unable to be broken. In Leviticus, we see that the Levites were to season each sacrifice with salt. Indeed, the term for it was salt of the covenant of God. A covenant not to be broken. Mark 9:49 For every one shall be salted with fire, and every sacrifice shall be salted with salt. Everyone of us believers is in covenant with God through the blood of Christ.
So then what does it mean to have your speech seasoned with salt? We are under a covenant of salt with the Lord. All of our actions and words should reflect Him. He is glorified by what we do. Sometimes we are the only “bible” someone sees. Our words need to be spoken with the love of Christ. Our words should be given to us by the Holy Spirit when we witness. Our words are to be tempered, seasoned if you will, by our Lord. When we answer each one regarding the Blessed Hope we have in Christ, it should be His words we speak, words given to us by the Holy Spirit, spoken gently in love. Seasoned with salt.
