The best teacher is one in whom the pupil feels the presence of religion as a concrete, natural thing. The best Sunday-school teaching is an initiation of the pupil into sacred things, and initiation is a process of admitting one to a society of persons and fellowship. Many persons have been asked to say what in their experience as Sunday-school pupils most influenced them for good. The reply, apparently the invariable reply, has been, “The personality of the teacher rather than the content of formal instruction.” Nothing in the way of methods or advice can take the place of wholesome, winning personality that actually lives in the realities of the Christian experience and truly admits pupils into the fellowship of this life.[1] Opportunity It is the aim of the Sunday school “gradually to bring to completeness or perfection the worthy qualities and characteristics of each pupil, and repress the unworthy, to the end that he may do the work and exert the influence of a true Christian in his environment.” The Junior period is a time when the Sunday-school teacher is given a unique opportunity for helping to realize this aim. In the child’s physical life this is a time of slow growth and bodily vigor, which makes possible a degree of concentration in work and study not to be expected in the earlier years. It is a time when the memory is both strong and retentive, and the child may make the greatest treasures of holy writ his own for all time if he learns them in these years. The brain cells are still plastic, though hardening rapidly. It is therefore easy to get the child to act along suggested lines, and through incentives and rewards to secure that regular, voluntary repetition of the right act which is necessary for the formation of a habit. The fact that this is the great habit forming and fixing period of life makes evident at once the large opportunity and the corresponding responsibility of the Sunday school in its relation to Junior children. Teachers, while endeavoring to exemplify the virtues which they inculcate, should constantly aim to help their pupils to form such habits as regular Bible reading and study, church attendance and attention (which is even more important), punctuality, cooperation, industry, thoroughness, perseverance; cheerful, systematic, intelligent giving, reverence and orderliness. It is tremendously important that the children shall form character building habits at this time; for “whatever is found in the life as habits of thought, feeling, and action at the dawn of adolescence will then be greatly magnified and strengthened.”
