The Sunday school is the biggest force of the church in the life of the boy. At times he refuses to attend the stated worship of the church, but if the Sunday school be in the least interesting he will gladly attend it. Its exercises and procedure must, however, be interesting, and rightly so. The boy has the right to demand that the time, his own time, which he gives to the Sunday school, should be utilized to some decently profitable, pleasurable end. Education, even religious education, is not necessarily a painful process. Discipline of mind or body has ceased to be a series of disagreeable, rigid postures or exercises. Medicine has no virtue merely because it is bad to the taste, and modern medical usage prescribes free air and warm sunshine in large doses in place of the old-time bitter nostrums. Even where the boy spirit needs medication, the means employed need not be sepulchral gloom, solemn warning, other-world songs, and penitential prayers, with great moral applications of the non-understandable. The germs of spiritual disease give way before the sunshine of the spirit, just as fast, if not faster, than the microbes before the sun. The Sunday school, then, should be a happy, joyous, sunny place, brimful of ideas, suggestion and impulse; for these three are at once the giants and fairies of religious education, and are the essential elements of character-making. To produce all of the above, three things are needed: adequate organization, careful supervision, and common-sense leading. The first is imperative, because all education is a matter of organization. The second is part of the first, as supervision is the genius of organization. The third is fundamental, for all expression--true education--depends on the teacher or leader, whose innate idea of the fitness of things keeps him from doing, on the one hand, that which is just customary, or, on the other hand, that which may appear to be just scientific. The science of yesterday should be the tradition of today; that is, if we are making progress in educational processes. Today's science also should be fighting yesterday's for supremacy. Common sense lies somewhere between the two. The only two of these three Sunday school essentials that this chapter deals with are organization and supervision. The Sunday school should be a kind of a religious regiment, martial both in its music and its virtues for its challenge to the adolescent boy. Now, every regiment, in peace or war, is properly organized with battalions, companies, and squads. Everything is accounted for, arranged for, and some one definitely held responsible for certain things--not everything. The organization covers every member of the regiment; so should the Sunday school.
