Maintain Self-control

The scholars in your class may be perverse and stubborn, inclined to evil, they may severely test your patience, and yet their hearts are soil into which you may sow heavenly seed that will bear a harvest for good. If the teacher is not imbued with the Spirit of God, he will become discouraged, lose his self-control, and, by an impatient word, by a severe reprimand, may cut off all his influence, and make a failure of his work.—Testimonies on Sabbath-School Work, 44.CSW 180.1
