Therefore, Paul's instruction to let our speech always be seasoned with grace suggests that we should demonstrate the same grace we have experienced through Jesus Christ in our tone, attitude, and behaviour in our interactions with others. This means avoiding being rude, boastful, arrogant, proud, or conceited. Instead, we should listen patiently to those with whom we may disagree, seeking to understand them before seeking to be understood, as Stephen Covey advises in his book "The 7 Habits of Highly Effective People." This is what it means to show grace, not just in our words but also in our actions.
