Well-balanced minds and symmetrical characters are required as teachers in every line. Give not this work into the hands of young women and young men who know not how to deal with human minds. They know so little of the controlling power of grace upon their own hearts and characters that they have to unlearn, and learn entirely new lessons in Christian experience. They have never learned to keep their own soul and character under discipline to Jesus Christ, and bring even the thoughts into captivity to Jesus Christ. CSW 92.2
There are all kinds of characters to deal with in the children and youth.... Many of those children have not had proper training at home. They have been sadly neglected. Some have been left to do as they pleased; others have been found fault with and discouraged. But little pleasantness and cheerfulness have been shown toward them, and but few words of approval have been spoken to them. The defective characters of the parents have been inherited, and the discipline given by these defective characters has been objectionable in the formation of characters. Solid timbers have not been brought into the character building. CSW 92.3
There is no more important work that can be done than the educating and training of these youth and children. The teachers who work in this part of the Lord's vineyard need to learn first how to be self-possessed, keeping their own temper and feelings under control, in subjection to the Holy Spirit of God. They should give evidence of having not a one-sided experience, but a well-balanced mind, a symmetrical character so that they can be trusted because they are conscientious Christians, themselves under the chief Teacher.—Fundamentals of Christian Education, 266, 267.
