In biblical times, people believed that demons could enter into people to cause them to err, much like how Satan entered Judas to caused him to betray Jesus. When a mute spoke after Jesus cast out the demon in him, the crowd was amazed saying “It was never seen like this in Israel!” The Pharisees were dumbfounded how Jesus had command over the demons. And later, the seventy disciples marveled that the demons were subject to them by the authority of Jesus! You see, no one doubted demons existed then, they were more astonished that the demons could be commanded to leave a person in the name of Jesus! This is the dispensation that we are in today; Jesus charged that these signs will follow those who believe in His name, that we would cast out demons and wrestle against spiritual forces that cause infirmities of the body, mind and soul. Glory to God! Hallelujah!
