This is a true scripture (Proverbs 13:24) quoted to cause Christians to believe that they must “spank” or “cause pain” to their children who don’t do the right thing--in many cases to excuse abuse. But it was given under the Old Covenant or Mosaic Law and is not repeated in the New Covenant or its record in the New Testament. It in no way relates to “Fathers do not exasperate your children.” (Ephesians 6:4) or “love believes all things…” (1 Corinthians 13:4-8)
We teach children that hitting is not the way to resolve issues; then we hit them.
While it’s true that a qualification of being an elder is to be one “whose children believe and are not open to the charge of being wild and disobedient”, the same scripture also states that a qualified person is not to be a “striker” (literal Greek translation). (Titus 1:5-7)
When a large child on a playground hits or in other ways hurts a smaller child, what do we call the larger child? Right. A bully. We tell them to go pick on someone their own size. Yet many teach that a man who is five or six times larger than a small child should hit the child when he or she doesn’t live up to expectations.
