Sorry Brother, but you have too much conjecture for me to even start to respond to your teaching.
I also think this site is for conversing, asking questions, and etc. not for sermons and teaching your theology. we have many different beliefs and understandings of the Word of God here on this forum to try and teach others your ways. Make a point, opinion, ask questions on how others understand certain passages and discuss them in light of the Word of God.
God doesn't need for the devil to get out of a person so He can heal them. We have the power , in the name of Jesus to cast out demons. Why would god give us the Holy Spirit, if it wasn't to give us the authority to lay hands on the sick and see them recover? Why would He tell us the works that He did, we could do also? Did Peter ask God to heal the lame man at the gate beautiful, or did he do it by the authority he had been given, such as I have give I thee, He said, in the name of Jesus Christ rise up and walk. Sorry I must go for now, can talk later, if you wish.
