Thought from Today's Old Testament Passage:
Thus saith the Lord unto me, Go and get thee a linen girdle, and put it upon thy loins, and put it not in water [Jeremiah 13:1].
I just can't help but smile at this. I don't think that Jeremiah was putting on weight. In fact, I would think he had been losing weight. God told him to get a girdle and wear it. But it wasn't because he was getting fat—a girdle wasn't worn for that purpose in that day. You see, today a girdle is used to try to achieve an hourglass figure when it is more like a barrel! In that day a girdle was something worn to bind up the flowing garments to ready oneself for service.
The girdle is a sign of service. The Lord Jesus spoke of His servants having their "… loins … girded about …" (Luke 12:35). That is, they are to be ready for service. You remember that He girded Himself with a linen cloth and began to wash the disciples' feet. This had a twofold meaning: He, the great Servant, was preparing them for service by washing their feet so they could have fellowship with Him. For if you don't have fellowship with Him, you can't serve. Service is fellowship with Christ. It is not teaching a Sunday school class, singing a solo, or preaching a sermon. Service is fellowship with Christ. It is being cleansed and used for what He wants to do. God doesn't use dirty cups or dirty vessels.
