Is All Sickness Demonic?

Clearly not.

Jesus cast demons out of some people with certain ailments, such as deafness and lameness, while He healed others of the same ailments without casting out a demon.  Therefore, we cannot say that all sickness is due to the direct action of a demon in your body.  However, all sickness does have its origin with Satan, regardless of how it comes to you.

In Mark 7:32-37, Jesus healed a deaf man without casting out a demon.  In Mark 9:17-29, Jesus healed a boy with a deaf spirit in him.  So you cannot say that deafness always is or always isn’t caused by an evil spirit.

The crippled man at the gate called Beautiful was healed in Acts 3:1-16 without any reference to a demon being cast out.  However, the crippled woman in Luke 13:11-16 was bound by a spirit of infirmity.  Again, this can go either way.

The women in Luke 8:2 were healed of “evil spirits AND infirmities,” which would indicate that not every woman who had an infirmity had an evil spirit.

You are not necessarily having a personal visitation from the devil just because you are sick.  But sickness is called the oppression of the devil in Acts 10:38.  Sickness is part of the devil’s kingdom, not God’s.  You have been redeemed from Satan’s kingdom (Colossians 1:12-14).  Sickness was not part of God’s original creation, all of which He declared to be good or very good.  Sickness will not exist in heaven or the new earth where Satan is not present.  That should tell you right there who the author of sickness is.

Suppose I put a rock on the accelerator of my car and aim it at your house.  My car plows into your house and demolishes your living room.  You say, “I’m not mad at the guy who wrote that healing book.   It was a car that wrecked my living room, not a person.”  That is no different from saying, “It’s just a virus going around.  It’s not the devil.”  Who do you think invented viruses, which steal, kill and destroy?  Satan is the author of sickness, regardless of whether or not he personally puts it on you.  Thus, in a sense, all sickness is satanic.  However, not all sickness is caused by the direct action of demons.  Sin brought trouble, including sickness, into this world.  Sickness will be here until Satan is banished.  It is part of life on Planet Earth.  However, you do not have to have any of it yourself – sickness does not have to be part of your life on Planet Earth.
