“One of the greatest and richest of all your blessings will be that which comes if you teach as you should, and train as you should these choice spirits that our Heavenly Father is sending to the world in this latter day. … Do not leave the training of your children to the public schools. Do not leave their training to the Primary, to the Sunday School, to the [Church’s youth organizations]. They will help you and make a fine contribution but remember what God himself has said . . . [see D&C 68:25–28].
“This is not a threat, my brethren and sisters, that is the kind and loving advice of our Heavenly Father who knows all things and understands and realizes what it means when children are allowed to grow up without this training” (Teachings of Presidents of the Church: George Albert Smith, p. 235-236).
