During college, I took a physical education course in boxing. The instructor matched each student with someone of approximately the same height, weight, and reach. But my assigned partner kept missing class, so I frequently ended up boxing a fellow twenty pounds heavier. (I had loose teeth the whole quarter!)
Three one-minute rounds seemed to take forever, especially when the opponent danced around the ring and I connected only once every several punches. Fatigue set in quickly.
I learned a lesson that quarter that has stuck with me ever since: You're drained of more energy by swinging and missing than by landing a solid punch.
Now that I am in church ministry, I see a number of people who are worn out in their ministries while others put in a lot more time yet remain refreshed. I suspect that the differences rest not in their commitment level or energy level as much as how well their ministry job fits. When expended energies "connect," people last longer.
