Should I Be Afraid of Demons?
If it is done properly, through the power of the Holy Spirit and in the name of Jesus, there is no reason to fear. Demons are subject to the followers of Jesus through His name and He has given us power and authority over Satan and all demons. We show no mercy to demon spirits.
Do Demons Leave When one is Born Again?
Both experience and logic tell us that Christians have demons that do not leave when a person is born again. If they did that person would no longer be plagued with sickness & disease, anxiety, fear, depression, lust, addictions and so on.
These demons need to be cast out in order to free each believer to effectively conform to the image of Jesus and fulfill their mission here on earth.
