Our daughter was 3 at the time. I don't exactly know what prompted her to say this but she asked verbatim "If the devil is the one who causes all the badness in the world, then why doesn't God just annihilate him and everyone could be happy?" We were floored that her little brain could be so analytical and that she would even entertain a thought like this at her age. Maybe she is gifted; I still don't know.
