The man here is mowing a very big field. And he's accomplishing it one step at a time. Nothing he's doing is newsworthy. No one is going to be on the sidelines cheering him on. And if he were to stand still and look around, gazing over the entire field, the size of the task he has might feel overwhelming. But he's not doing that. He's moving forward, bit by bit, and with persistence through time, the job will be done. And then, of course, it will soon need to be done again. And again. And again.
Very little in life is lasting. Most of what we face and accomplish is temporary. But there is great and lasting worth in the doing, when it's done well. And that's what we're called to focus on and be responsible for: doing what needs to be done, and doing it well. If we want the result to be beautiful in every way, though, I suspect we need to do whatever we do in love, from love, and for love. That's the great motivator and goal both. Whatever the field of endeavor, that's the ultimate secret and source of power for good work.
