The deep significance of joy in the Christian life is hardly understood. It is too often regarded as something secondary; whereas its presence is essential as the proof that God does indeed satisfy us, and that His service is our delight. In our domestic life we do not feel satisfied if all the proprieties of deportment are observed, and each does his duty to the other; true love makes us happy in each other; as love gives out its warmth of affection, gladness is the sunshine that fills the home with its brightness. Even in suffering or poverty, the members of a loving family are a joy to each other. Without this gladness, especially, there is no true obedience on the part of the children. It is not the mere fulfillment of a command, or performance of a service, that a parent looks to; it is the willing, joyful alacrity [Brisk and cheerful readiness.] with which it is done that makes it pleasing.
