              not take upon himself responsibilities outside of his schoolwork
            
            
              [301]
            
            
              which will so tax him physically and mentally that his nervous
            
            
              system will be unbalanced, for by this course he will be unfitted
            
            
              to deal with minds and cannot do justice either to himself or to his
            
            
              students.
            
            
              Sometimes the teacher carries into the schoolroom the shadow
            
            
              of darkness that has been gathering on his soul. He has been over-
            
            
              taxed and is nervous, or dyspepsia has colored everything a gloomy
            
            
              hue. He enters the schoolroom with quivering nerves and irritated
            
            
              stomach. Nothing seems to be done to please him; he thinks that his
            
            
              pupils are bent on showing him disrespect; and his sharp criticisms
            
            
              and censure are given on the right hand and on the left. Perhaps
            
            
              one or more of the students commits errors or is unruly. The case is
            
            
              exaggerated in his mind, and he is severe and cutting in his reproof
            
            
              of the one whom he thinks at fault. And the same injustice afterward
            
            
              prevents him from admitting that he has taken a wrong course. To
            
            
              maintain the dignity of his position, he has lost a golden opportunity
            
            
              to manifest the spirit of Christ, perhaps to gain a soul for heaven.
            
            
              It is the duty of each teacher to do all in his power to present
            
            
              his body to Christ a living sacrifice, physically perfect, as well as
            
            
              morally free from defilement, that Christ may make him a co-worker
            
            
              with Himself in the salvation of souls.
