(Pro 18:13 KJV) He that answereth a matter before he heareth it, it is folly and shame unto him.
Hearing is an act of the will. Our ears work all the time. I can’t turn mine off. In spite of that handicap my mind can do a good job of putting up barriers. We hear when we want to. I don’t know if you have ever worn hearing protection. You see them at shooting ranges, on airplanes and I have even seen them being worn by musicians. People who work around loud machines wear them. One of the interesting things about them is you can still hear. It is possible to be wearing a device designed to protect your hearing but be able to hear the person speaking next to you. It happens because you are paying attention.
So? This is something we can all work on. We need to recognize there are times when it is important that we listen. It is not easy. It can wear us down. It is still important.
