Spankings and beatings do not make good children. Love and correction do.
Spankings and beatings create fear, especially since research shows that they are usually carried out in rage, frustration and anger. But then, you'd have to be a real 'sicko' to sit quietly and calmly with your child and explain 'why' you have to beat them first.
If God was so clever and all knowing, he would have worked out for himself that spanking kids does not equal teaching them anything.
We have all been in classes where a teacher can control an unruly class with a look. Strength of character and disipline, ie detention can do that. Fear of annoying such a person was enough to control a class. I remember a tiny little science teacher, a woman. NO ONE EVER MESSED UP IN HER CLASS, EVER!
Smacking is unnecessary for a parent to control kids.
My sons are all bigger than me. If they don't do what I say, I give them a computer ban or TV ban, or take away a privilige. I scowl, when normally I'd smile. I mean what I say.
I learnt NOT to smack children. It doesn't work. So why doesn't the God of the Bible know this?
