I absolutely believe in possession and demonic influences and oppression toward humanity. But what do I know? lol I'm not myself the Creator of this universe. Yet I still believe my own beliefs. I won't infringe on others' beliefs with my own, I refuse. I believe there is a Holy Spirit, and evil spirits. They respectively positively and negatively influence our moods, thoughts, behavior and if possible, our actions. I choose to operate within the power of the Holy Spirit alone when I have a choice. If I didn't have a choice, or was deceived, I would operate under an evil spirit. It seems black and white to me. But that's just me. And a few others.
