Lam 5:16
16 The crown is fallen from our head: woe unto us, that we have sinned!
KJV
Rev 3:11
11 Behold, I come quickly: hold that fast which thou hast, that no man take thy crown.
KJV
I do not carry the same thought that you can only be saved once, that would not leave room for the back slider to return back to Grace. I do not believe once saved always saved. I find no scripture to cover once saved always saved either. If youc an provide I would be pleased if you would share it with me please. (Sincere request, I hate the lack of voice infliction)
Devotiontobible, thank you for causing me to seek deeper for understanding. I totally understand what you are saying about the physical control thing.
Now as to demon possession, a demon (evil spirit) what ever you want to call it, it is clearly not God. If you indeed have the Holy Ghost intact, you can NOT be possessed by a demon spirit. Light and Darkness can not dwell in the same place.
A demon spirit can cause us to be depressed, or oppressed through suggestive thoughts. It is not possible for the spirits or the devil himself, to read your mind or your heart. However, they can barrage your mind with thoughts that become consuming and make it difficult to pray, or to be joyful, etc...
This leaves a door open for "pressed down, shaken together, and running over" blessing of the Holy Ghost to be exhausted in you. Meaning the negative thoughts are consuming more of your time, hence causeing you to have serious spiritual issues.
God can not live where sin is. If you, through these thoughts, fall into unrepented sin, then there grows room for darkness and the possibility changes.
If you have unrepented sin in your life God can not dwell in a dirty vessel.
God Bless
