“Grace” is “favor,” “graciousness.” If, if I were doing this a literal translation according to usage, I would translate it, “Let your speech always be gracious,” or, “Speak graciously.”
Colossians 4:6 (cont’d.)
… seasoned with [what?} {salt} [to mean what you say and to say what you mean], that ye may know how ye ought to answer [or speak to] every [what?] {man}.
That’s your covenant of salt. And that covenant of salt was originally instituted by God, from God’s point of view. And, as long as you walk in the light as He is the light, that covenant is applicable. He will carry it out.
When I put all this together, in the royal household of God to which you and I belong, the scriptures like God will “supply all … [of our] need according to His riches in glory by Christ Jesus,” “Beloved, I wish above all things that thou mayest [what?] prosper and be in health,” why: because we’re attached to the root by a covenant of what? {Salt.} “Let your speech be … seasoned with [what?] {salt}.”
That, ladies and gentlemen, I think is, at least in part, the greatness of the covenant of salt that God established in the beginning with Levi; then, with the kingdom of David; finally—on the
day of Pentecost—with His household of believers, the royal household of God, the Jesus men and women, you. His covenant with you, it is salted: He means what He says and He says what He means, and God never breaks His covenant.
