No other conclusion is compatible, either with the scope of the lesson or the facts of the case. The sower in this story neither helps the seed to grow nor understands how the growth proceeds. The parable is spoken in order to show that, while men are employed at first to preach the word and at last to gather the fruits in the conversion of their brethren, they can neither perform the converting work nor trace the footsteps of the quickening Spirit in the secrets of a human heart. By this similitude the Lord represents the extent and the limits of human agency in the progress of his kingdom. Having made our way through the difficulties of the parable, and found the key-note of its interpretation, we turn again to its terms for the sake of observing and applying the practical lessons which it contains. The sower sows the seed; the seed is the word; the hearts of those who hear it are the field. Parents make known the Gospel in their families, ministers in the congregations, teachers in the schools. These sowers lose sight of the seed from the moment that it drops into the ground. It sinks and disappears; they must go away and leave it. They sleep by night,[57] and attend to other matters by day; they cannot see how it fares with the Gospel in a neighbour's soul. They cannot put their hand to the work at this stage to help it: the seed must be left to itself in the soil. [57] Here, as in the case of the tares, the sleep of the husbandman implies no culpable negligence either in the natural or spiritual sphere. "Sind wir am Tage recht wach; dann, mögen wir Nachts ruhig schlafen."--_Dräseke, vom Reich G._ At this point the likeness between the natural and the spiritual is exact and obvious. When you have made the Gospel of Christ known to some in whom you are interested, you are precisely in the position of the agriculturist who has committed his seed to the ground. If you think of the matter when you lie down, or when you awake, you discover, perhaps with pain, that you do not know whether the seed is swelling and springing or not: and that though you knew its condition you could not reach it, to stimulate the process. It is out of your hands, and out of your sight. It is not, however, out of mind, when it is out of sight; and your own helplessness may draw forth a more eager prayer to the Almighty Helper. In this way it is when we are weak that we become strong; it is when we are made most keenly sensible of our own weakness that we cast our care most fully on the Lord. The law that shuts the sown seed out from us, shuts it in with God. One door closes; but the closing that hides the seed in its seed-bed from our eyes and separates it from our hands, leaves it open to His sight, and pliant to his power. The moment that the seed is sown, he takes it out of our sight, but then and thereby he brings it into his own. It is away from us, and with God.[58]
