Help with removing a spirit???

First, don't stick to any one formula. There is no magic word to get rid of a spirit. You have to take authority, but to do so, you have to actually believe you have that authority. You don't use Jesus name out of fear. You use it because you know the power in that name and you know that Jesus has made you an equal with Him. If you can't take authority get a pastor. A lot of pastors don't believe in this stuff anymore, so find someone in the area who does. If you really think it's a spirit, get rid of it before you can't anymore.
