Read and consider this article (The Eschatology of Parenting) on the consequences of shirking our parenting duties. It says in part:
A parent who will not discipline a child for disobedience, or who is inconsistent in doing so, is teaching that child not to expect consequences for behavior. In short, a parent who will not discipline is denying the doctrine of hell.
I don’t think he’s taking things too far. I think we are just stunted think that ramifications only last until our child dies. The article is brief. Please read it.
