Do you ever get the impression that a young baby is more aware of what is going on than you think it should be? One of the pastors I respect most theorizes that the spirit is mature at birth, and is capable of being influenced by things that can't possibly be grasped by its developing mind.

Not only that, but unclean spirits are capable of much more than what we talk about. It can get freaky once you start to see into the spiritual realms. We have authority through Christ, but we need to use it to be effective.
