"Like vinegar to the teeth and smoke to the eyes, so is the sluggard to those who send him." Pr. 10:26, ESV.
Have you ever had a co-worker or subordinate (or employee) who was lazy? I have. It's miserable - trying to get things accomplished with lazy people is like pulling teeth. It takes a special kind of patience not to blow up at them, or just do the work yourself.
But turn the picture around. Have you ever been that lazy person? I'm sure you have, at least from time to time. In fact, it's very likely that we are all going to be given tasks and jobs next week, and we have the opportunity to be like a mouthful of vinegar to our supervisors, clients, or managers.
Whether you will be the sender or the sent one next week, be careful. Be careful whom you send, and for what tasks - don't get smoke in your eyes! If you must work with lazy people, don't be surprised; don't let them foil the critical part of the operation. If you work for somebody else, watch yourself closely: are you lazy? Are you unreliable? Will you complete the mission? Don't be vinegar in somebody's mouth - the kind of thing they spit out in disgust.
Today, let's be humble enough to consider whether and when we tend to play the sluggard. And let's repent of that folly.
