(_e_) To pretend to be wiser or better versed in Bible lore than one really is. In Bible teaching, real knowledge is real power—but a manner that assumes to know what it does not is only the lion’s skin on the ass’ head. (_f_) To neglect thorough study. Wherever there is good teaching there will be at least two students. One will be the teacher. Witness Dr. Arnold, of Rugby. (_g_) To neglect private prayer in the teacher’s preparation. Said old Martin Luther, “_Bene arâsse est bene studuisse_.” (_h_) To depend upon lesson-helps in the class. Crutches are not becoming to an able bodied man. But some teachers bring out the lesson crutches on Sunday morning and hobble through Sunday-school on them. (_i_) To expect the superintendent to discipline each class. He is no more responsible for class order than a commanding general for the order of a corporal’s guard. (_j_) To use the lesson verse by verse, ending each with the Æsopian interrogation, “_Hæc fabula docet?_” _II. Purpose and Expectation._ It is a mistake (_a_) to seek only for a scholar’s conversion. If growth does not follow birth, death will. Upbuilding in Christ is one great purpose of the school. (_b_) To seek only to create interest in the lesson. There may be _deep intellectual interest created, and no spiritual interest_. (_c_) To teach for the purpose of performing duty. That robs the teacher of one chief essential to success—_heartiness_. (_d_) To teach for the purpose of inculcating one’s own peculiar religious views. Paul’s purpose was the right one—“to know nothing save Christ and him crucified.” (_e_) For the teacher to expect the pupil’s interest in the Gospel theme to equal his own. It is contrary to sinful nature. (_f_) To expect home work by pupils, unless it has been prepared for by patient effort. (_g_) _To expect conversion as the immediate result of teaching_, and to grow discouraged and abandon the work because the expectation is not at once realized. God’s way and time are his own. (_h_) _Not to expect conversion as the ultimate result of teaching_; and hence to fail to direct every effort to that end.—“In the morning sow thy seed,” etc. _III. Thought and Action._ It is a mistake (_a_) _to think teaching easy_. It has taxed the noblest powers of the noblest men. (_b_) To think it an insignificant or puerile employment. The two greatest names of the ages, heathen and Christian, were nothing if not teachers: Socrates—Immanuel. (_c_) To think the Sunday-school a children’s institution only. The three great Christian institutions are the home, the church, the Sunday-school, and the constituency of each is the same. (_d_) To be irregular in attendance at Sunday-school. (_e_) To be unpunctual. (_f_) To be lax in discipline. (_g_) To fail in example, whether in connection with school work or daily life. EDITOR’S OUTLOOK. INGENUITY IN LOCAL CIRCLES.
