Here is a ref that Farkel did not quote:
Awake 1979, May 8:
Jehovah, a God of love, counsels parents: “Do not be irritating your children, but go on bringing them up in the discipline and mental-regulating of Jehovah.” (Eph. 6:4) Discipline—instruction or training that molds—can be an expression of love. We read: “‘My son, . . . whom Jehovah loves he disciplines.’ . . . True, no discipline seems for the present to be joyous, but grievous; yet afterward to those who have been trained by it it yields peaceable fruit.” That is so in the family, too.—Heb. 12:4-11.
But does loving discipline include a parent’s use of spanking? According to God’s Word, it definitely can, when the spanking is an expression of and in a manner consistent with love. Consider these verses from the inspired book of Proverbs:
“Folly is bound up in the heart of a child, but the rod of discipline will drive it far from him.” (22:15) “Do not withhold discipline from a child; if you punish him with the rod, he will not die. Punish him with the rod and save his soul from death.” (23:13, 14) “He who spares the rod hates his son, but he who loves him is careful to discipline him.” (13:24)—New International Version.
HERE IS THE SHOCKING PART! SAME ARTICLE:
Whether they do it with the hand, a wooden ruler or some other type of appropriate “rod,” parents are authorized by God to use spanking in lovingly disciplining their children.
(Could this type of "rod" include an electrical cord? According to them I believe it could...)
Here is one from 1988 WT, Dec 15th:
“Spare the Rod, but Note the Consequences” was the title of an article appearing in The Natal Mercury, a South African newspaper, lamenting the modern trend of holding back physical punishment from children at home and in school. Who is responsible for this changed attitude toward spanking? Professor Smythe, a pediatrician at the University of Natal, South Africa, places the blame squarely on child psychologists. “Usually on delving into the roots of an emotional issue,” Smythe explains, “one finds the change in attitude starting with psychological dogma. At first violently opposed to any form of physical punishment, then appalled by the consequences of the indiscipline resulting from a creed of no frustrations and no inhibitions.”
Smythe advocates a balance. “Extremes of permissiveness are as bad as extremes of punishment,” he notes, “but the fact that remediation is easier with the overdisciplined than the underdisciplined child favors leaning on the side of discipline when in doubt.” The professor emphasizes that the motive for giving physical punishment should be loving concern for the child’s present and future welfare.
Such advice is not new but a return to the infallible Biblical guidance: “The one holding back his rod is hating his son, but the one loving him is he that does look for him with discipline.”—Proverbs 13:24; see also Proverbs 23:13, 14.
