The "parents" are unrepentent and now the girl has revealed that she, too, does not recognize the necessity of repentence.
God rejects the unrepentent and through His apostle Paul, He reminds us of this.
You never answered the question about the parents that are divorced. Or having adulterous relationships. Or the single mom living with her boyfriend. Does the school ask each parent what sins they are currently involved in they have not repented for? If not why not? You see where it gets foggy?
Answer this .... If this was your childs school and they knew of all your secret sin would your child be at school this morning?
