“The young should be controlled by firm principle, that they may rightly improve the powers which God has given them. … Since they cannot always have the guidance and protection of parents and guardians, they need to be trained to self-reliance and self-control.

“We have an army of youth today who can do much if they are properly directed and encouraged. We want our children to believe the truth. We want them to be blessed of God.
