There is great challenge in preparing pupils for the time when they will be leaving Sunday School at age twenty.
Many thoughts come to the teacher. For example: "Has the teaching given the pupils real preparation for this forward step?" Sometimes there is, on the teacher's part, a concern that what they have learned will not continue to benefit the departing pupils. This is the time to rely fully on divine Truth, the source of the teaching. The truth that has come from God cannot suddenly be cut off or rendered inadequate —any more than God Himself can be obliterated.
When the teacher prays, "Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord," Ps. 19:14; his thought is turned to the direction and inspiration of the divine Mind, God. When the weekly Lesson-Sermon from the Christian Science Quarterly is thoroughly researched by the teacher and the class, the needs of the class emerge. Then inspired thoughts come to the pupils and the teacher. Everyone shares and grows. The teacher can have confidence that the good work done in the class will continue to bless everyone.
