How can a demon dwell within a believer who has the Holy Spirit?
Many believe that anybody who has the Holy Spirit is immune from demonic bondage. This theology usually stems from a faulty belief that the soul (mind) and the spirit are the same things. The moment we are born again, our spirits are reborn and the Holy Spirit is united with our spirit. The soul (mind) of a man is not instantly reborn as the spirit is, but rather we are told to be transformed by the renewing of our minds, which doesn’t happen instantly. Our souls is where the dirt lies, and where the demons dwell, not our spirits. Therefore, there is no reason left to believe that a Christian is immune from demonic bondage, because their souls are usually on the dirty side until they are renewed over time. If the soul and the spirit were the same things, you would instantly be a perfect person, never to sin again, once you are born again. There would be no ‘evil’ left in you, no desires to do wrong, and you would hate it bitterly because you would be perfect in your mind/soul and unite
