“Call upon Me, and I will answer thee.” “I will instruct thee and teach thee in the way which thou shalt go; I will guide thee with Mine eye.”[399] “Even unto the end of the world” “I am with you.”[400] [Sidenote: _The Highest Preparation_] As the highest preparation for your work, I point you to the words, the life, the methods, of the Prince of teachers. I bid you consider Him. Here is your true ideal. Behold it, dwell upon it, until the Spirit of the divine Teacher shall take possession of your heart and life. “Reflecting as a mirror the glory of the Lord,” you will be “transformed into the same image.”[401] This is the secret of power over your pupils. Reflect Him. _Co-operation_ “WE ARE MEMBERS ONE OF ANOTHER” In the formation of character, no other influences count so much as the influence of the home. The teacher’s work should supplement that of the parents, but is not to take its place. In all that concerns the well-being of the child, it should be the effort of parents and teachers to co-operate. [Sidenote: _Co-operation of Parents_] The work of co-operation should begin with the father and mother themselves, in the home life. In the training of their children they have a joint responsibility, and it should be their constant endeavor to act together. Let them yield themselves to God, seeking help from Him to sustain each other. Let them teach their children to be true to God, true to principle, and thus true to themselves and to all with whom they are connected. With such training, children when sent to school will not be a cause of disturbance or anxiety. They will be a support to their teachers, and an example and encouragement to their fellow-pupils. [Sidenote: _Sustaining the Teacher_] Parents who give this training are not the ones likely to be found criticizing the teacher. They feel that both the interest of their children and justice to the school demand that, so far as possible, they sustain and honor the one who shares their responsibility. [Sidenote: _Criticism_] Many parents fail here. By their hasty, unfounded criticism the influence of the faithful, self-sacrificing teacher is often well-nigh destroyed. Many parents whose children have been spoiled by indulgence, leave to the teacher the unpleasant task of repairing their neglect; and then by their own course they make his task almost hopeless. Their criticism and censure of the school management encourage insubordination in the children, and confirm them in wrong habits.
