Satan had put an unclean spirit, or devil, in that man. Jesus was not angry with the poor man, but He spoke to the unclean spirit, and said, 'Be silent, and come out of him.' He came out, and the man became well. The people in the synagogue were greatly surprised. They said, 'What thing is this? He commandeth even the unclean spirits and they obey Him.' When the service was over, the people who had seen the miracle went home, and talked to everybody about what they had seen. Some of them had sick friends, and some had friends with unclean spirits, and they longed to bring them to Jesus. But it was the Sabbath, and they would not bring them until the evening, at which time their Sabbath came to an end. So as soon as the sun set that Sabbath day, a great crowd was seen standing round Peter's house. It seemed as if all the people of Capernaum must be there! They had brought their sick friends, and laid them down at the door. And Jesus put His hands on the sick people, and healed them all. In the east there is a dreadful illness called leprosy, and the people who have it are called lepers. No doctor can cure it. At the time when Jesus lived on the earth, lepers were not allowed to come into cities. And they had to go about with nothing on their heads, and with their dresses torn, and with their mouths covered over; and when they saw anybody coming, they had to call out, 'Unclean! unclean!' One day when Jesus went into a town a leper saw Him. The poor man came to Jesus and knelt down before Him, and fell on his face. And he said, 'If Thou wilt, Thou canst make me clean.' And Jesus put out His hand, and touched him, and said to him, 'I will; be thou clean.' And as soon as Jesus had said that, the leper was well. Sin is just like leprosy. A baby's naughtiness does not look very bad; but that naughtiness spreads and gets stronger as baby gets older, and nobody but Jesus can take it away. Jesus Christ's body must often have felt very tired, for crowds followed Him about all the time. They came from Perea, and from Judaea, and from other places too, to see the wonderful new Teacher. And Jesus preached to them all, and healed their sicknesses. The most wonderful sermon that was ever preached in all the world is called the Sermon on the Mount, because Jesus sat down on a hill to preach it.
