Two fathers.
Father 1: His son lies to him so he spanks him and makes him stay in his room for the rest of the day. Someone asks the father, "Why is the son confined to his room?" The father replies, "Because he lied to me and that is his punishment." "But who decided that punishment," they inquire? The father responds, "I did. And I will appeal to him later to be reconciled by repenting. If he refuses he will remain in his room, separated from fellowship with me."
Father 2: His son lies to him so he kills him. Someone asks the father, "Why is the son dead?" The father replies, "Because he lied to me and that is his punishment." "But who decided that punishment," they inquire? The father responds, "He did." They argue, "But, your son didn't decided the punishment for lying, you did." The father continues, "No, that just IS the punishment for lying, it is the nature of act that causes him to be killed. But, I'll still ask him to repent for lying so we can be reconciled." They continue, "But, huh, er, you already killed him..why would you ask him to repent for his lies if you already killed him? He can't repent now!" The father asserts, "He should have thought about that before he lied. It is his fault." "Well, it is his fault for telling a lie, I agree, but he isn't at fault for not responding to your requests now, you took away that ability when you decided to kill him," they protest. The father replies, "Naw, he made that decision, now leave me alone so I can be patient with him, hold out my hands to him, and ask him to respond." "Ok, sure, whatever you say. But I'm still calling the cops, cause you're crazy," they say.
