A section of an article called "The Rod And Reproof" by Stephen Key:
Contrary to the well-known teachings of Dr. Benjamin Spock, and the teachings of many who have rejected the Word of God, the rod is a necessary instrument in the discipline of our children. So important is that rod that God tells us in Proverbs 13:24, "He that spareth his rod hateth his son."
The rod of discipline is not easy to use.
The world has so corrupted the concept "love," that our deceitful hearts would readily say that it is love to let a child do his own thing, so to speak.
And I would have you mothers notice that the mother is mentioned specifically in this text. Because the father's calling is to provide for the family, the calling of the early discipline of your children falls primarily upon you mothers who are at home. That is one reason you are mentioned specifically. But I would submit that there is another reason you are mentioned in connection with this calling to use the rod and reproof. If the father's stronger character generally induces him to "provoke his children to wrath," which Paul warns us fathers against in Colossians 3:21, does not the mother's softer and generally more tender nature lean toward the opposite evil? Would you mothers attempt to correct your children with a few harsh words, or with a mild, "If you quit that right now, I'll give you a piece of candy?"
The Scriptures, however, teach something quite different. Woe be unto you parents who refuse to heed the Word of God in the discipline of your children! For God tells us to love, not hate. "He that spareth the rod hateth his son." Love necessitates correction with the rod and reproof! If we love our children, God says that we must administer discipline and correction.
The rod is a generic instrument which might take several different forms. It was an instrument that was used as the shaft of a spear. It sometimes denoted a scepter, the mark of authority used by one who ruled. But the rod was also an instrument used to administer corrective and physical discipline. For us it might be a stick or a switch or a firm ruler. But whatever that instrument may be, it is a means to return the wayward child to the right course.
We must also note in this connection, that rightly to use the rod on our children requires love. All too often, where physical discipline is exercised, it is not done out of love either for God or the child. We who must administer such discipline to our covenant children, must do so under God's authority and with His manner and attitude. That attitude is revealed in Hebrews 12:6-8: "For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? But if ye be without chastisement, whereof all are partakers, then are ye bastards, and no sons." God does not abuse us in His chastening. He loves us.
There is a reason also in this connection that God prescribes the use of the rod. It takes just a little time and effort to get the stick out. And for us to reflect God's attitude of love through our reactionary, impatient, sinful flesh, it is necessary that we slow down and think about what we are doing. Slapping your children around the head and beating on them with your fists, whipping them or beating them with any object close at hand, or anything of the like, is nothing more than abuse of the children whom God has entrusted to your care. And if that has been your ungodly method of punishing your covenant children, you must repent before God and before your children this day!
God instructs us to use the rod in love.
The chastisement of the rod, used in love, is a chastisement quickly and mercifully inflicted. Although our children may question it, there is no punishment more mercifully inflicted than the rod. It is God's method, which is quickly over, with no need to look with disdain upon a corrected child for hours and even days. The rod is not a punishment that keeps the child in mom's and dad's "doghouse." Furthermore, God's call for the use of the rod takes into account his or her physical welfare. God created a particular part of the body capable of receiving the impact of the rod without injury. It is evident that God did not create every part of the body to receive the blow of the rod. When we parents administer the discipline of the rod in love, then we do not do so to injure. That means that we are not to strike our children in the back, where we may cause injury to the spine or the kidneys, nor in the stomach, nor on the head or hands; but on the flesh of the backside where, if the rod is used properly, it may be keenly felt.
And if you ask, what about the older children, the text speaks to that also. We may agree that the rod is good for young children. But how should we discipline our teenagers? Well, you may be surprised to hear that teens are not to be excluded from the use of the rod when necessary. It is striking in the text, that Solomon implicitly calls for the use of the rod and reproof until the child is an adult. The term "child" refers - as is clear in the Hebrew term used - to a child who has reached the age of independence, who is ready to move out of the house and marry.
You will find, when you administer discipline to your child as God commands and as you nurture that child to receive more and more responsibility and to become more and more dependent upon God, that the rod will not often be necessary with your teenager. As a covenant child matures in the way of loving discipline, under the diligent use of rod and reproof as a child, he learns to experience joy and peace in the home. He grows in the knowledge and understanding of the Word of God, of the gospel of salvation in Jesus Christ. He realizes that obedience to God is the way of happiness. And the rod is less frequently necessary as a means to instruct. But it is still a means.
But along with the rod must be reproof.
"The rod and reproof." When the rod is used, God has ordained discipline to be twofold. Proper Christian discipline is not dictatorship, rule by might with the rod alone. To separate these two is to ask for the chastisement of God to fall upon your head. Eli gave the reproof, but spared the rod; and he had to suffer the torment of hearing that his sons were slain by the wrath of God, and the ark of the Lord was taken by the Philistines. Others, contrary to the Word of God, use the rod alone. Now, there are many times when a matter of discipline can be handled by reproof alone. The indication of Proverbs 17:10 is, if reproof works the sorrow of repentance, then let the rod be spared. If not, use the rod and let not thy soul spare for the child's crying. But never use the rod without reproof.
Reproof is verbal instruction in godliness.
The child must not only be steered away from the path that leads to hell, but he must be shown the error of his way before God and he must be instructed in righteousness. Our children must be taught to evaluate their own specific actions in the light of the Scriptures. They must be taught to bow before the authority of God. They must be taught why the thing that they did was wrong in the eyes of God. Biblical discipline requires words. How much do you think you would get out of my preaching, if all I did was stand in the pulpit from week to week waving my arms and making contortions with my face, but never saying a word? The message of the gospel cannot be communicated by mere gestures or by pounding the pulpit. Nor can the instruction in Christian discipline be communicated if all that our discipline amounts to is a painful pantomime with a stick. The wrath of God was exercised toward us, that we might hear those precious words, "I love you in Christ Jesus." And even now, when we experience the chastisement of God, it is to lead us in the way toward heaven.
When we understand that precious truth, then we ought to express our love to our children especially when we are called to use the rod. We must reprove them, expressing our love for them. We must assure them that the rod is not administered out of hatred, but out of a heavy heart that loves that child in Christ. What a terrible thing it is when confessing Christian parents beat their children, but fail to reprove them and to point them to the love of Christ. How utterly wicked it is for a parent to spank a child only to leave him like a dog to lick his sores. It is no wonder when such children run to their rooms, slam their doors, and mutter under their breaths, "I hate you." Such an attitude expressed by a parent who uses the rod, but never reproves in love, has no semblance whatsoever to the attitude God expresses in chastening His spiritual children. God demands the rod and reproof.
And we ought not forget that belonging to reproof is prayer, which brings parent and child close to God. The necessity of prayer in the discipline and instruction of our children cannot be overemphasized. For one thing, we parents must repeatedly approach God seeking forgiveness for our failure to exercise discipline as He has ordained. We need to do that today and every day. We need to pray for grace to obey His Word and to bow humbly before His wise instruction. We need to pray for much wisdom in dealing with our covenant children. For we know that if God were to reward us according to our iniquities, every one of our children would walk the way to hell. And we need to pray for our children. We ought to do that not just generally, but specifically, naming each one by name and praying for the specific needs of each child and bringing before God the specific problems we face with each child. More than once, I have heard the testimony of a child of God, speaking of his Christian father whose discipline fell far short of the biblical standard. But one thing that father did, in the presence of his children, was to fall on his knees to beseech God's forgiveness for himself and God's mercy towards his children. Such prayer leaves on the mind and soul of a child an impression that will never leave him. In prayer also, we are to reflect the love of Christ toward us. He prays without ceasing, serving as our faithful and constant Intercessor by His Holy Spirit.
In all things the Lord God calls us to reflect Him, also in the administering of Christian discipline to covenant children. And He says to us in Proverbs 3:11, 12: "My son, despise not the chastening of the LORD (despise not His use of the rod on you); neither be weary of his correction (of his reproof): For whom the LORD loveth he correcteth (He reproves); even as a father the son in whom he delighteth."
