Use the powerful name of Jesus Christ to cast them out anon!
They must obey when you use the name of Jesus Christ. Get born again, then you will have both the power and authority to use His name. They fear this so much, that's why they don't want you getting born again, because then you will be so powerful against them. I know exactly how you feel, I cast them out using Jesus name and they flee like the cockroaches they are!!
