So to protect us from hurting our souls God gives us emotional pain and that emotional pain is in the form of guilt related to an ethical choice. There are other kinds of emotional pain but the emotional pain associated with wrong ethical choices is called guilt. That's a warning to us that we shouldn't keep doing it for one, and second that we are responsible because we've transgressed a moral law. Now I think the fact that every human being experiences guilt is a very important argument in favor of the Christian view of man because some people have suggested that guilt is something that you manufacture. You just invent it.
People invent guilt to manipulate other people.
I ask two things if guilt is simply something invented by humans to control other human beings. I can't do that. I can only appeal to something that's already there. It's called manipulation. When you manipulate something you are working with something that already exists.
