Satan does not want Gods people to understand what they have access to. The same God that backed up His servant David, and delivered a giant into His hand, is the same God that you have with you at all times. Evil spirits and demons tremble at the name of Jesus Christ. James 2:19 James 4:7 Luke 10:17 Rather than allow fear to creep in, why not say, Father, this evil spirit did not enter in here without your foreknowledge, so what are you saying or trying to show me? I am of the mind that one would do better to not give the entity the satisfaction of your attention, but rather turn to God, and most assuredly invoke the name of Jesus Christ.
These being hate you and would see you dead. So why's it standing there calling you names if it's so powerful?! Because it has no power over you unless you give it to it. A Spirit filled Christian is the (next to) last one that an evil spirit wants to encounter.
Engage this thing, it sounds like you have a gift. Don't engage the entity other than to take authority over it, engage the Lord. There's got to be a reason behind these manifestations. Perhaps they happen so often because the Lord is trying to show you something...and you're not getting it?!
Confront this thing and set it at the Lords feet. Ok Lord, what's going on and why?
They can not hurt you. Why do you think that their main weapon is deception? That's all they have brother. You just keep clinging to the Lord and you'll be safe.
