You didn't answer the question. That's ok. I will ask again. What does one do with all their gentle talk and handing out chores when the child still simply refuses to do as they are told? I suppose you give them more chores and words when they refuse to do the chores you already gave them?
You know I have a couple verses too. Written by Solomon, the man who had a gift of wisdom straight from God Himself. I tend to think that if he came to this conclusion WITH A GIFT of WISDOM form God that it is probably good to follow.
Proverbs 23:13-14 -Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.
14 Thou shalt beat him with the rod, and shalt deliver his soul from hell.
Of course you don't jump to physical discipline immediately. Only an idiot would follow that plan. That doesn't mean you don't use the rod when you need to.
Some of the worst kids I know are the ones whose parents had some mamby pamby, limp approach to discipline centered around "time outs" and "losing priviledges" instead of wearing out their behinds when they acted up.
