Have you ever noticed that many people tend to have “selective hearing,” but very few seem to have “selective speaking”? There are some folks who are just more interested in being heard than 
actually listening.
There are a number of proverbs that speak to this matter of speaking. Consider these three. “Do you see a man hasty in his words? There is more hope for a fool than for him” (29:20). “In the multitude of words sin is not lacking, but he who restrains his lips is wise” (10:19). Paraphrasing Proverbs 18:13, “If I speak about a matter before I hear, I’m a fool.”
God calls upon Christians, “Let every man be swift to hear, slow to speak, slow to wrath” (1:19). Someone observed that there is a reason God gave us two ears and one mouth! We should listen twice as much as we speak! Which one gets more use in your life and mine? The New American Standard Bible begins James 1:19, “This you know.” Do we?
