^^ Which is exactly why, even if the Bible HAD meant "rod" as an actual whipping instrument....it would be foolish for us to take that one reference out of context and decide God wants us to beat our kids.
You know....that whole story... in the very beginning of the Bible...about having free will... you know, Adam, Eve, etc....? Pretty sure it started that way for a reason. I'm not even convinced it's a literal historical record of the first two people on earth, but strongly, strongly symbolic. Clear message: We are not robots. We have discernment, we make decisions, we have free will. We are entrusted with that free will.
