"But allowing that the two eldest are now beyond your control, they were not when God sent you the light that you were indulging them to their ruin; that you should discipline them. But you have three younger children who are walking in the way of sinners, disobedient, unthankful, unholy, lovers of pleasure more than lovers of God. Your youngest son is following in the footsteps of his brother. What course are you pursuing toward him? Do you train him to habits of industry and usefulness? Are you taking up your fearfully neglected work and redeeming the past? Do you tremble at the word of God? 2T 624.1"
"Train up a child in the way he should go: and when he is old, he will not depart from it."
The EGW passage directly addresses the principle of child training and discipline, echoing the sentiment of Proverbs 22:6, even though it doesn't explicitly quote it.
"Your neglect at home is wonderful in one that has God's written word and also testimonies borne especially to you, showing your neglect. Your boy does as he pleases. You do not restrain him. You have not educated and trained him to bear his share of the burdens of life. He is a bad boy because of your neglect. His life is a reproach to his father. You knew your duty, but you did it not. He has no convictions of the truth. He knows he can have his own way, and Satan controls his mind. You have made your children an excuse to keep you at home; but, Brother B, the things of this world have come first 2T 624.2"
"The rod and reproof give wisdom: but a child left to himself bringeth his mother to shame."
Both passages discuss the importance of discipline in raising children and the negative consequences of neglecting this responsibility. Proverbs 29:15 highlights the shame brought by an undisciplined child, while EGW describes the negative impact of the father's neglect.
