Any believer has the right to use the authority and power in Jesus' name to cast out devils and to lay hands on the sick for healing. Norvel Hayes teaches that the key is for a believer to gain knowledge regarding how to use that power effectively. Norvel explains the kind of knowledge we need; the consequences if we don't have that knowledge; where and how to use our knowledge to cast out demons, receive our own healing, and heal the sick with the authority Jesus gave us.
