I think we are forgetting that evil spirits CAN inhabit things. In both Luke, Matthew and Mark, they talk about Jesus casting out the evil spirits from the crazy man, and the spirits asked to be cast into the swine. So, there is both a case of inhabitation, casting out spirits, and reinhabitation of another object, although in this case the swine were living.
However, 2 Chronicles 31:1 - ....all Israel who were present went out to the cities of Judah and broke down the wooden images, and threw down the high places and the altars...
Isaiah 2:20 - In the day a man will cast away his idols of silver, and his idols of gold, which they made, each for himself to worship..
Isaiah 30:22 - You will also defile the covering of your images of silver, and the ornament of your moulded images of gold. You will throw them away as an unclean thing; You will say to them, "Get away!"
Isaiah 31:7 - For in that day every man shall throw away his idols of silver and his idols of gold - sin, which your own hands have made for yourselves.
It seems clear that God would have us destroy that which we make an idol of - and many symbols of religions are made of precious metals and are certainly idols. So if we have them in our homes, it would seem safe to say that God would want them removed.
In the first verse, the people of Judah pulled down the high places along with the images. Ephesians 6:12 says - For we do not wrestle against flesh and blood, but agqainst principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the high places."
Therefore if images and icons are connected with the high places, and the high places are the homes of the hosts of wickedness, could it not be said that items we consider to be just items, may well be inhabited with evil spirits.
For we are not the houses we live in, but we do live IN them and venture out to carry the Word of God and spread His touch to the world, why not the same principle with objects and evil spirits?
