Each is doing something different, but all are contributing to the end result. There are 22 players in a football game. Yet, only one man at a time handles the ball. Sometimes the cameraman misses the ball carrier, and those of us who see only the newsreel have no conception of what is really happening on the playing field.
Similarly, I believe that I have a part in the unfolding of God’s plan for the universe, and that I contribute my part to the realization of that plan, though I cannot see the plan in its entirety. Consequently, I think that I have an obligation to do my best, whatever my role may be. That role may change from time to time, as my abilities are demonstrated, in much the same way that a football player may be shifted from guard to tackle or from end to back, as the developing team requires.
