“Excellent speech is not becoming to a fool, Much less lying lips to a prince.”
Proverbs 17:7 NKJV
If we are truly to become like Christ, then our speech must be cleansed and purified along with the rest of us. Excellence of speech belongs to the wise, not to the fool. Christians are heirs to the Kingdom of God, who will sit and rule with Him, judging the world and angels (1 Cor. 6:3, 12), do we believe our words have no power? Jesus was careful about every word He ever spoke, He was never careless with His speech and neither should we be.
Every idle word will be accounted for on the soon-coming Day of Judgment (Matt. 12:36). Christ does not say “every EVIL word” but idle ones, those that are spoken carelessly and without thought. The muttering under the breath, the useless and worthless speech that’s given little to no thought, those words that seem to flow from us before we have a chance to even think. These idle words portray our true heart condition moreso than our normal speech, for “out of the abundance of the heart the mouth speaks (Luke 6:45). Isaiah had this realization when he stood before God in the throne room, “Because I am a man of unclean lips, And I dwell in the midst of a people of unclean lips”
(Isaiah 6:5). How important our speech is when we are called to be proclaimers of the gospel and messengers of God’s holy word!
