One might wonder how such a topic could be used in a daily Bible study; of what value is it? Would Christians be moved to search the subject in a paranormal sense?[i] We often speak casually about some other person we meet being our double, our twin, maybe even our second-self, but do we really mean that? Why is appearance and behavior so important? If a child bears my name, am I more concerned with how they move and speak?
