Jesus Healing The Possessed Man animation video. He went down to Capernaum, a city of Galilee, where He would eventually live, and He taught regularly in the synagogue on the Sabbaths. The people of Capernaum were astounded at His teaching because He spoke with authority. One time in the synagogue "there was a man who had a spirit of an unclean demon." While Jesus was speaking, the man loudly shouted, "Let us alone! What have we to do with You, Jesus of Nazareth? Did You come to destroy us? I know who You are—the Holy One of God!" Even evil spirits knew who Jesus Christ was, and were terrified of Him. They knew Jesus had the power and authority to cast them out, which is exactly what Jesus did. He told the spirit to shut up and get out. "Be quiet, and come out of him!" In its last act of rebellion, the spirit convulsed the man. "And when the demon had thrown him in their midst, it came out of him and did not hurt him."
