we need to learn and teach to children and youth. Said Christ, “I sanctify myself, that they also might be sanctified,” [ John 17:19 .] This is the work that ever devolves upon every teacher. There must not be any hap- hazard work in this matter, for even the work of educating the children in the day schools requires very much of the grace of Christ and the subduing of self. Those who naturally are fretful, easily provoked, and have cherished the habit of criticism, of thinking evil, should find some other kind of work that will not reproduce any of their unlovely traits of character in the children and youth, for they have cost too much. Heaven sees in the child, the undeveloped man or woman, with capabilities and powers that, if correctly guided and developed with heavenly wisdom, will become the human agencies through whom the divine influences can cooperate to be laborers together with God. Sharp words, and continual censure bewilder the child, but never reform him. Keep back that …
"And for their sakes I sanctify myself, that they also might be sanctified through the truth."
Ellen White directly references John 17:19 in this passage.
