no what denominational means is that i believe in Christ and God and all the Christian beliefes but i dont believe you should worship in a sertian way i believe you can worship how ever you want to
My point was that if you are non denominational, it implies that you must either be rejecting or agreeing with the tenets of most of the denominations, which either largely agree or disagree with demonic possession in the context you gave, or you are just independently believing possession isn't possible within that context, thus not choosing a specific denomination.
God cant see sins and our bodies are Gods temples (i we are Christians)and deamons are sinnful so God wont let them in yes we do sin but since Jesus died on the cross we can be saved from our sins
