I'm an adult now, and my parents have passed away. We did when we were young. I do believe that children need discipline and guidance - they do not always require a whipping though. I think the thing that works best is discussing first, grounding (or taking away privileges) second.

Where does God say this? I don't believe He would support such a barbaric form of punishment.

I was spanked (as in slapped on my butt with my parents' bare hand) but never whipped.

God said no such thing. I seriously wish people would actually see what the Bible says for themselves.
