Truth is tho, nowhere in Scripture is a Christian delivered from a demon. Yes the Soothsayer woman, and Simon The Sorceror were dealt with, but they were not Christians. So the question remains, why are Christians getting delivered from demons in their "solarplexes" and strongholds inside them and etc, when there is no deliverance of Christians in The New Testament; yes unbelievers and those first getting saved, but other than that we have no Scripture to support deliverance ministry of Christians.
While I believe supernatural warfare is real, the devil is real, and demons, and that Jesus told us to caste them out. My issue is with Christians becoming preoccupied by demons, because to me its bondage, the Scripture says, "Fix your eyes on Christ, the Author nad Prefector of your faith," (Hebrews 12:2) and "I count all things lost but knowing Jesus.." (Philippians 3:9). If something takes your eyes off Jesus and has you fixated on it, then it is error.
