The idea of girded loins suggests readiness for service or endevour (ISBE). In this case, we are to be ready to serve the Lord with truth. People need to hear the truth about their soul's condition. We should be ready at all times to share the truth about God's Word, and to do it truthfully. Not only is truth something we ought to give away or share, but it is also something that must remain close to us. Two words: "Conspiracy Theory." Just type in 9/11 conspiracy on a search engine and you will see the hundreds of articles, videos, etc. dedicated to such untruths about the September 11 terror attacks. How easy it is for Christians to get entagled by so many untruths. It is amazing the amount of time that is wasted by Christians who do not gird their loins with truth.
