Under no circumstances should the teacher manifest partiality. To favor the winning, attractive pupil, and be critical, impatient, or unsympathetic toward those who most need encouragement and help, is to reveal a total misconception of the teacher’s work. It is in dealing with the faulty, trying ones that the character is tested, and it is proved whether the teacher is really qualified for his position. * * * * * [Sidenote: _Responsibility_] Great is the responsibility of those who take upon themselves the guidance of a human soul. The true father and mother count theirs a trust from which they can never be wholly released. The life of the child, from his earliest to his latest day, feels the power of that tie which binds him to the parent’s heart; the acts, the words, the very look of the parent, continue to mould the child for good or for evil. The teacher shares this responsibility, and he needs constantly to realize its sacredness, and to keep in view the purpose of his work. He is not merely to accomplish the daily tasks, to please his employers, to maintain the standing of the school; he must consider the highest good of his pupils as individuals, the duties that life will lay upon them, the service it requires, and the preparation demanded. The work he is doing day by day will exert upon his pupils, and through them upon others, an influence that will not cease to extend and strengthen until time shall end. The fruits of his work he must meet in that great day when every word and deed shall be brought in review before God. The teacher who realizes this will not feel that his work is completed when he has finished the daily routine of recitations, and for a time his pupils pass from under his direct care. He will carry these children and youth upon his heart. How to secure for them the noblest standard of attainment will be his constant study and effort. [Sidenote: _Self-Improvement_] He who discerns the opportunities and privileges of his work will allow nothing to stand in the way of earnest endeavor for self-improvement. He will spare no pains to reach the highest standard of excellence. All that he desires his pupils to become, he will himself strive to be. * * * * * The deeper the sense of responsibility, and the more earnest the effort for self-improvement, the more clearly will the teacher perceive and the more keenly regret the defects that hinder his usefulness. As he beholds the magnitude of his work, its difficulties and possibilities, often will his heart cry out, “Who is sufficient for these things?” [Sidenote: _Our Source of Help_] Dear teacher, as you consider your need of strength and guidance,—need that no human source can supply,—I bid you consider the promises of Him who is the wonderful Counselor. “Behold,” He says, “I have set before thee an open door, and no man can shut it.”[398]
