Bob and Ricky, I've been praying about the things you spoke of. The other day a curious "street" cat wandered into my house, and as my wife and I don't want animals inside I quickly chased it out (I'm also allergic). From what I hear you saying, whatever power you do or do not grant them, these spirits are entering your home and family. I would not tolerate that a moment. Were I in your shoes I would start a short fast, say one or two days, and be praying both against them (how else can one wield the "sword of the Spirit" if one does not speak?) and to the almighty Savior and God, to rid and cleanse your home. What Luther said concerning sin applies here: One cannot stop birds from flying around one's head, but one can keep them from making in nest in one's hair. Bob, you said, Demons are real but they are not real powerful. They depend on illusion, superstition and fear to cause you harm. Take away the fear and superstition and they have nothing. Scripture tells us the devil (with his demons) is a liar, murderer, tempter, seducer, accuser, deceiver, and thief. He does have access to our minds / hearts by way of projecting thoughts and images to our minds -- these are often what the "fiery darts" consist of. The shield of faith enables us to resist such: In the name of Christ I refuse and resist such thoughts, etc. How else will you resist the devil? You can't push him away. The shield of faith is an active force of the knowledge of God's keep power, believed in the heart and expressed verbally. The sword of the Spirit is the power of God's own word projected into the spirits, and they do flee, as His might and glory terrifies them. The fact that spirits can materialize so as to be seen, and can influence physical objects, is sufficient power for the saint to war against it when it enters his / her home and family. Deliverance folks and exorcists are not what is needed. Resistance must come from the people being oppressed, and as it is your own flesh and blood being so affected, even if not you yourself, they've crossed the line.
