Angela is right. While demons and demonic oppressions do exist, only JESUS can bring deliverance. Far too many churches are focused on theology... without THEO.
MariaJoy, these things might be scary and understandably you'd want to be prepared and avoid possibilities of demonic possession but hey, when you seek Jesus, you will find that the devil won't even dare touch you. Fear is what feeds the devil to, continually bother people with stuff Jesus already saved us from.
Seek Jesus and what He has done on the Cross for your deliverance. He has the answer to absolutely EVERYTHING. Not that I know everything but, at least, I know He has delivered me from all kinds of oppression I've faced.
I have ran across and come in contact with deliverance teaching, about demonic oppression, spiritual house cleaning, Christians having demons and items having demons attached to them. Does anyone have experience with this teaching? Is it true?
