The Third Principle defines the work of nurture.

"Nurture must care for both nourishment and activity."

1. The Watch Care over Nourishment.

   Nourishment is the general term for all that upon which the life feeds. It is given both consciously and unconsciously and is absorbed in like manner, but in its effect upon the life, the unconscious nourishment has greater power.

   1. Unconscious Nourishment.

      1. The first factor in unconscious nourishment is personality.

         Just as truly as the physical life is nourished by life, so is the mental and the spiritual. Standards of living, ideas, a sense of values, opinions, do not come from text-books but fathers and mothers. The lesson from the printed page may fail to gain entrance, but the lesson from the teacher's life, never. This explains the success of many a humble mother and the failure of many an intellectual teacher. It is at the very heart of all work for another.

         Its first message is a personal one. It tells the worker that his life is more compelling than his voice; that the Word must again become flesh to give it authority. It tells him further that if he is to be the bread of life to growing souls, his own pasturage must not be things, but in reality, the living Christ.

         The other message applies to his work. While every life that touches his will always carry away something from the contact, the most helpful human life can never suffice for another's nourishment. Each soul needs the complete Christ for itself. The amazing thing among parents and teachers is their unconcern over His absence from the lives of the children. Years pass, and precept, lesson and admonition are given, while Christ, the Life, is not definitely and personally offered. "According to their pasture so were they filled." Is not this the explanation of so many meagre lives?

      2. The second factor of unconscious nourishment is environment with its subtle atmosphere.

         The importance of environment is found in this great law, that life tends to become like that which is around it. So strong is the tendency that the only escape from conformity lies in real struggle. This a little child rarely puts forth, and an adult not always, for it is far easier to follow the line of least resistance and "be like other people."

         Growing out of this power of environment comes the problem of all philanthropic and religious work—how to overcome the influence of harmful surroundings. The need is obvious when the surroundings are vicious, yet the home does not need to be in the slums to injure a growing life. It only needs to be Christless. This may seem a very radical statement, but it is nevertheless true. Arresting the highest development is as truly an injury as giving to life wrong direction. Has not a plant been positively injured when its most beautiful possibilities are unrealized because of unfavoring conditions? Is not a body, undersized and stunted because of lack of fresh air and food, as truly deformed as though the back were bent? Has not that soul received the most cruel of all injuries, when its divinest possibilities can never be attained either because of spiritual starvation or misdirection? The Church and the Sunday School attempt to furnish a counteracting environment, but it is infrequent and brief. The only power which can render this temporary, religious environment mote effective in influencing character than a harmful, permanent one, is the Divine. A church building or a Sunday School session of itself, can accomplish little, placed over against a home. Methods of grading and forms of worship are impotent in themselves. It is only a living Christ, actually vitalizing the lesson and the sermon and the plan of work Who makes them efficacious.

         If this be so, then the teacher who goes to the home itself to press the claims of a personal Savior on the father and mother, has after all reached the heart of the problem of environment.

      3. The third factor of unconscious nourishment is the Superhuman Power.

         This thought has been suggested in connection with personality and environment, but it demands separate emphasis. It is not an easy thing in the stress of the visible to remember the greater power of the Invisible. The most earnest Christian worker is sometimes overwhelmed by discouragement or, again, unduly confident because of the perfection of system and method, forgetting that God knows no obstacle, and that He alone can put life into a plan of work.

         But though God uses men and methods, He does not always so approach a life He deals directly with a soul through the influence of the Holy Spirit, and life receives its most holy nurture in those sacred hours. Therefore, the highest service permitted a Sunday School teacher is to pray effectually for the brooding Spirit to rest upon the pupils in his class. The mother can do nothing which shall mean so much for the precious life in her arms as learning, herself, the secret of prevailing prayer, for, "If we ask anything according to His Will, He heareth us; and if we know that He heareth us, whatsoever we ask, we know that we have the petitions which we have asked of Him." Therefore, O Lord, "Teach us to pray."

   2. Conscious Nourishment.

      This is definite instruction so given to a life that it is appropriated. A large part of attempted instruction is never taken in. "I have told you over and over again," says the despairing mother, but telling does not always involve receiving. Placing nourishing food before the boy does not necessarily mean stronger muscle and purer blood. He must eat and digest it. Teaching, to be nourishment, requires first, careful adaptation of the subject matter, then presentation in such a way that the mind will voluntarily reach out, lay hold upon and assimilate it. God again gives the key to real teaching in the word "engraft." Its process in the physical and mental world is identical. First, the delicate adjustment, then a vital union, and lastly, new life resulting.

2. The Watch Care over Activity.

   We have considered nurture in its work of supplying the best nourishment to growing souls, and now its care for activity must be noted. Since the subject will be discussed more fully in a succeeding chapter, only the necessity for the nurture will be considered here. This necessity appears in the four-fold result of activity.

   1. New Experiences.

      This is the first result to the child from ceaseless movement of hands and feet and eager eyes. In early life he is not conscious of seeking the new experience, he only wants to be in motion. In later life, energy is definitely put forth for some desired end. But whatever the motive, experiences helpful or harmful, according to the sort of activity, result, and they enter character at par value.

   2. Growth or Increase in Size.

      Activity is necessary before anything given to the body or the soul can become a part of life. Food must be acted upon by the digestive, circulatory and assimilative organs to make it bone and muscle and nerve. The mind must think upon the fact in order to add it to the store of knowledge. The heavenly vision must be obeyed before Christian experience is enlarged by it.

      But there is another aspect of this same thought. Just as truly as activity must precede assimilation, so truly does assimilation follow activity. It may be stated
