Now the reason of this is very plain. We have forgotten the parable of the lily. Violent efforts to grow are right in earnestness, but wholly wrong in principle. There is but one principle of growth both for the natural and spiritual, for animal and plant, for body and soul. For all growth is an organic thing. And the principle of growing in grace is once more this, "Consider the lilies _how they grow_." In seeking to extend the analogy from the body to the soul there are two things about the lilies' growth, two characteristics of all growth, on which one must fix attention. These are-- First, Spontaneousness. Second, Mysteriousness. I. Spontaneousness. There are three lines along which one may seek for evidence of the spontaneousness of growth. The first is Science. And the argument here could not be summed up better than in the words of Jesus. The lilies grow, He says, of themselves; they toil not, neither do they spin. They grow, that is, automatically, spontaneously, without trying, without fretting, without thinking. Applied in any direction, to plant, to animal, to the body or to the soul this law holds. A boy grows, for example, without trying. One or two simple conditions are fulfilled, and the growth goes on. He thinks probably as little about the condition as about the result; he fulfills the conditions by habit, the result follows by nature. Both processes go steadily on from year to year apart from himself and all but in spite of himself. One would never think of _telling_ a boy to grow. A doctor has no prescription for growth. He can tell me how growth may be stunted or impaired, but the process itself is recognized as beyond control--one of the few, and therefore very significant, things which Nature keeps in her own hands. No physician of souls, in like manner, has any prescription for spiritual growth. It is the question he is most often asked and most often answers wrongly. He may prescribe more earnestness, more prayer, more self-denial, or more Christian work. These are prescriptions for something, but not for growth. Not that they may not encourage growth; but the soul grows as the lily grows, without trying, without fretting, without ever thinking. Manuals of devotion, with complicated rules for getting on in the Christian life, would do well sometimes to return to the simplicity of nature; and earnest souls who are attempting sanctification by struggle instead of sanctification by faith might be spared much humiliation by learning the botany of the Sermon on the Mount. There _can_ indeed be no other principle of growth than this. It is a vital act. And to try to _make_ a thing grow is as absurd as to help the tide to come in or the sun rise.
