Yes it can! Many physical ailments, afflictions and diseases are caused by demonic spirits. When demons are cast out they can be commanded to repair all damage done to the person. A strong indicator that an ailment is the work of a demon is that medical doctors are unable to identify a cause and it does not respond to medical treatment. It might even move around to different parts of the body from time to time. It is important for an individual to reveal any mental, physical, emotional, or medical problems they are experiencing when completing the deliverance questionnaire so those issues can be addressed during their session(s).
