My speech has an enormous influence for good or ill and is a sure guide to character. The power of what I say is indisputable. Consider the billions spent on therapy because of what others said about us when we were young. Jesus can fix that, but the effect is seen in the natural world. What I say to others matters.
What is the impact of speech? It has the power of life and death. That sounds extreme but it is true. Words can kill. Words can give life. Will I choose words the bear fruit of life?
The tongue” is used throughout Scripture in both literal and metaphorical ways, especially in Psalms, Proverbs, and James. The tongue is a “small part of the body” (James 3:5), yet Proverbs 18:21 says it “has the power of life and death.” This holds true whether we’re speaking of spiritual, physical, or emotional “life and death.”
We should keep in mind that the word tongue is often a reference to the spoken word. This is a special kind of figure of speech called metonymy, in which one word stands in for another, closely related word. A common example of metonymy is seen in this sentence: “The White House issued a statement.” Of course, the White House, as a building, cannot issue statements; however, in this instance, White House refers to the President, who lives there. In the same way, when Proverbs 15:4 states, “A deceitful tongue crushes the spirit,” tongue is a metonymy. Obviously, a literal, fleshly tongue cannot crush the human spirit, but the words the tongue produces can.
