We are composed of three parts: a body, a mind (soul) and a spirit (1 Thessalonians 5:23). The spirit of a Christian belongs to God, and their spirit is united with the Holy Spirit, but their bodies and minds (souls) can still be afflicted by evil spirits. Demons can, in some cases, even take over a Christian’s mind and speak through his lips (Matthew 16:22). I have seen demons control the psycho-motor functions of Christians, even putting them in a trance like state to speak through them.
BODY – Christians can have a sickness and disease that’s caused by demons (if not caused by other factors).
SOUL – Do you have a bad temper? That’s a demon. Is there mental illness in your family background? That is a demon. Do you have trouble serving God? That’s a demon. Do you have problems with bad thoughts? That is a demon(s) in your mind, or soul and needs to be cast out.
SPIRIT – Demons can surround your “Born Again” spirit like a glass jar surrounds its contents. The contents of the jar cannot get out until you remove the lid (demons). Deliverance can get rid of the demons. We cast them out of you in the name of Jesus.
