I was asked to conduct the funeral for a man who had helped develop the famous Boeing 747 aircraft. After the service, I spoke with the widow and commented on how remarkable it was that her late husband had helped build that marvelous machine. She said, "The truth is, he worked on one little switchbox smaller than a loaf of bread. That's all he worked on for 15 years. But when that 747 lifted off the ground for the first time, it was the happiest day of his life."
He worked on one small switchbox for more than a decade. Yet the huge plane couldn't have lifted off without this man's contribution. Often we see only our seemingly small efforts and feel we aren't very important. But when the great Kingdom of God "lifts off," we'll be thrilled to find out that all of our efforts were essential.
