“In order that the work may go forward in all its branches, God calls for youthful vigor, zeal, and courage. He has chosen the youth to aid in the advancement of His cause… Young men and women are invited to give God the strength of their youth, that through the exercise of their powers, through keen thought and vigorous action, they may bring glory to Him and salvation to their fellow men.”
