Here's a scenario. A person hears a voice. They think it is God. And this voice tells them to kill their own child. And they actually decide to do it! At that point, it is time for the police, perhaps the people in white coats, and child services to step in, right? Well...that's what happens in Genesis 22, making Abraham the paragon of bad parenting, at least according to the theologians of Family Guy.
I might have responded similarly!
