Jesus Christ knows our toil—the toil the Preacher complained about in Ecclesiastes—because he too has lived it. He too has experienced it. He too has suffered, and he has triumphed over that suffering. Consider that as you go about your work today.
We find that our Preacher is actually not very happy about his life or his work. He finally in Ecclesiastes 3:22 comes to the conclusion that we might as well enjoy work—not because it matters to God, but because, although we know God exists and is in charge, we have no idea whether God actually intends anything better for us than our current toil. There is a chance—more than a chance, in fact—that your work and your leadership really do matter to God—matter on that deep level where we all hunger to know that we are loved, known, and guided.
