Hate to break it to you brehs, but if you have demons that have been visiting you and your family, and this have been happening for generations, your family has been doing Christianity wrong.
For one, demons cannot possess what the Holy Spirit in dwells. And if you’ve been baptized into the body of Christ, the Holy Spirit dwells within you. You are physically the Church, you are physically the temple. You are physically the hands, eyes, ears, legs, and body of Christ. If this is the case, demons don’t play footsy with you. Additionally, being baptized into the body of Christ, puts a hedge of protection over you and your household.
Saw a documentary regarding the infiltration of the music industry with demonic entities which, not to get into much, but it was mentioned that Michael Jackson had a hall of mirrors at Neverland. The mirrors supposedly served as some sort of ritualistic gateway and had some type of significance with Aleister Crowley.
It’s all about gates, it’s all about doors. And whether you have then open or not. Your families partaking in these old vodun rituals and superstitions and synergizing them with Christian ritual is blaspheming the body of Christ and opening the doors for things to come and visit upon you and your families.
