(1) _The influence of lives that will bear the test._ In this doubting, critical period of life, the daily life of others is the unanswerable argument for or against the power of the gospel. If for no other reason than to establish the faith of her young people, the church ought to walk in white. (2) _Sympathy and confidence toward the pupil._ Some one has said that the word "hunger" will express the period of adolescence, and for nothing is the pupil so hungry as to be understood, appreciated, and trusted. The teacher is privileged to live into the life of the pupil at every point, and be the sympathetic friend who shall help him to work out his high calling in Christ Jesus. #34. Difficulties of the Senior Age.#--The very things that constitute the strength of this period present many of its difficulties. The greater mental power coming with increased reason and will is apt to give rise to self-sufficiency and the doubt already mentioned. Opinions are readily and dogmatically launched, and to reverse them wounds pride. Advice may be secretly welcomed and outwardly scorned. This is the period when there is danger that wisdom may perish if the youth meet an untimely end. But far more dangerous is the tendency toward the sowing of wild oats which is so often evident. A certain recklessness easily grows out of the disturbed emotional nature and excesses lie not far beyond. For all of these difficulties, faith and prayer, an attitude of helpfulness at every point, and the love that never fails, afford the only solution. #35. Results to be Expected.#--As the pupil emerges from the period of development into maturity, he ought to be "strong in the grace that is in Christ Jesus," with interest and love as broad as that of his Master, and "thoroughly furnished unto every good work." Test Questions 1. What are the general characteristics of the Senior Age? The years included? 2. Name three special characteristics. 3. How would you explain vacillating conduct during the early part of this period? 4. Name three opportunities of the Senior Age. 5. How may doubters be helped in this period? 6. What are two special needs of this period? 7. The chief difficulties? 8. What the results to be expected? Lesson 10 Maturity. The limited space of a single chapter permits only a suggestive discussion of this important period, so often neglected in the study of the pupil. #36. General Survey.#--(1) _Keyword, "Service."_ As childhood's task is absorption, and the task of youth adjustment, so the task of maturity is service. That which has been taken in must be given out again, enriched and enlarged by its stay in the soul. This is "the last of life for which the first was made," and to fail here means to miss the meaning of living.
