Can a Christian have demons?
The answer is yes. Consider the following analogy. Let’s say you own a vacation home in Hawaii, but spend most of your time living in another house in Maine. And let’s also say that while you are residing in Maine, a homeless man breaks into your Hawaiian home and moves in. The homeless man does not possess your house, but has determined to live there until you or law enforcement makes him move out. This is how it is with demons. Sometimes they are found where they do not belong.
In mainstream Christianity, whenever the Devil or a demon bothers the Christian, it is politely called oppression rather than being demonized. It seems forgotten that the demon must be inside so that he may oppress. It is wrong to assume that a demonized person is not a Christian. It is equally erroneous to assume a person has no demons solely because he or she is Christian and attends Church services. The safest abode a demon can have may be the Christian who thinks he is incapable of ever having demons.
In the Bible there are examples of persons who ought not to have demons but did. A man named Saul was anointed, given God’s Holy Spirit and made the first king over Israel, yet the Bible says he later became oppressed by an evil spirit [see 1st Samuel 10:1-11, 18:10-11 & 19:9-10].
At a synagogue, a spirit of infirmity was found in a woman whom Jesus called a daughter of Abraham. He also said that she was bound by Satan. Her physical condition was so bad that she could not stand up straight [see Luke 13:10-17]. For other instances where demons were found in people at a synagogue read Mark 1:23-24, Mark 1:39 and Luke 4:32-34.
The Bible says that Satan entered Judas Iscariot, who at the time was one of the chosen twelve disciples [see Luke 22:1-5]. A similar thing happened to another disciple named Peter. After Peter rebuked Jesus, He turned to Peter and said, “Get thee behind me, Satan” [see Matthew 16:21-23]. Satan filled the heart of Ananias, who was a member of the Church congregation at Jerusalem, with a lie [see Acts 5:1-6].
Unlike the lost person, the Christian is the only one given the right to be totally free of demons. Jesus told a woman, whose daughter had a demon, that deliverance was reserved for the children of God [see Matthew 15:21-28]. This means that the right to be free comes after entering God’s family and not before. Also, the freedom we receive needs maintenance. In his letter to the Ephesians, the Apostle Paul’s warns them to not allow the Devil a place in their life, which means that if the Christian isn’t careful this can happen [see Ephesians 4:26-27]. Paul also instructs them to put on the whole armor of God so that they may be protected [see Ephesians 6:11-12].
