To obey is better than sacrifice and to hearken than the fat of rams."

(1 Samuel 15:22)
The first and most important point in the training of children is to teach them the blessedness of obedience. They must learn obedience to properly constituted authority, which is the foundation of all moral excellency, not only in childhood, but all through life. If a child never learns to be obedient at home to the God-given authority of its parents, it will be disobedient to authorities of the Government.

Obedience to God is the very essence of a happy Christian life and if we would desire our children to be converted and be obedient Christians, we must teach them obedience at home from the very beginning. A child that has never learned obedience to its parents will seldom be an obedient Christian, if ever converted. Obedience to parental authority is essential to subjection to God's authority.
The parent's will should be supreme with a child, because the parent stands in the place of God in relation to the child. It is self-will, the inborn tendency of every child of Adam, that is the very essence of sin, and this will need to be brought into subjection to God. Upon parents, mothers especially, God has laid the task of beginning the work in childhood. Children should be trained to implicit and unquestioning obedience to their parents and to all authorities. We are living in the last days described in 2 Timothy 3, when disobedience to parents and all the various forms of self-will and rebellion are rampant everywhere, therefore it is all the more necessary that parents train their children in obedience.
