With such preparation as they can gain, thousands upon thousands of the youth and those older in years should be giving themselves to this work. Already many hearts are responding to the call of the Master Worker, and their numbers will increase. Let every Christian educator give such workers sympathy and co-operation. Let him encourage and assist the youth under his care in gaining a preparation to join the ranks. [Sidenote: _Opportunity for Education_] There is no line of work in which it is possible for the youth to receive greater benefit. All who engage in ministry are God’s helping hand. They are co-workers with the angels; rather, they are the human agencies through whom the angels accomplish their mission. Angels speak through their voices, and work by their hands. And the human workers, co-operating with heavenly agencies, have the benefit of their education and experience. As a means of education, what “university course” can equal this? [Sidenote: _Our Children’s Heritage_] With such an army of workers as our youth, rightly trained, might furnish, how soon the message of a crucified, risen, and soon-coming Saviour might be carried to the whole world! How soon might the end come,—the end of suffering and sorrow and sin! How soon, in place of a possession here, with its blight of sin and pain, our children might receive their inheritance where “the righteous shall inherit the land, and dwell therein forever;” where “the inhabitant shall not say, I am sick,” and “the voice of weeping shall be no more heard.”[396] _THE UNDER-TEACHER_ “_As My Father hath sent Me, even so send I you_” _Preparation_ “STUDY TO SHOW THYSELF APPROVED UNTO GOD” [Sidenote: _The Mother’s Opportunity_] The child’s first teacher is the mother. During the period of greatest susceptibility and most rapid development his education is to a great degree in her hands. To her first is given opportunity to mould the character for good or for evil. She should understand the value of her opportunity, and, above every other teacher, should be qualified to use it to the best account. Yet there is no other to whose training so little thought is given. The one whose influence in education is most potent and far-reaching is the one for whose assistance there is the least systematic effort. [Sidenote: _Lack of Preparation_]
