"The Youth to Act a Part in Church Work When the youth give their hearts to God, our responsibility for them does not cease. They must be interested in the Lord's work, and led to see that He expects them to do something to advance His cause. It is not enough to show how much needs to be done, and to urge the youth to act a part. They must be taught how to labor for the Master. They must be trained, disciplined, drilled, in the best methods of winning souls to Christ. Teach them to try in a quiet, unpretending way to help their young companions. Let different branches of missionary effort be systematically laid out, in which they may take part, and let them be given instruction and help. Thus they will learn to work for God. GW 210"
"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen."
The EGW passage directly reflects the principle of teaching and training new believers to participate in spreading the gospel, which is a core element of the Great Commission in Matthew 28:19-20.
