When asked for reasons why they think Christians can't be demon possessed one will usually hear, "It's not possible for the Holy Spirit and a demon to dwell in the same body," "It is unthinkable to believe the Holy Spirit would let a devil in a Christian's body, which is God's temple," A born again believer has been redeemed by the blood of Christ and because of that no devil can indwell him," etc., etc. But such arguments are purely emotional without a single Bible verse to stand on. These people have convinced themselves of something that is not true because of the repulsiveness of the question, but emotion and feelings do not make "sound doctrine."
