Its not being an "extreme christian" to have wisdom about carvings depicting spiritual entities. Unless you are spiritually blind, its simple and very obvious common sense. Alongside that is a realisation that Satan uses anything he possibly can to bring people, including christians, into demonic bondage.
1Cor10v19What do I mean then? That a thing sacrificed to idols is anything, or that an idol is anything? 20No, but I say that the things which the Gentiles sacrifice, they sacrifice to demons and not to God; and I do not want you to become sharers in demons.21You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the table of the Lord and the table of demons.…
If you have given it a home, you have effectively erected a temple over it! Behind every idol, there is a demon(s) and bringing it into your home, you have made an agreement with that idol/demon. Your own home itself has become the personal offering that you are making to the demonic power behind the idol.
Be assured, it will have an effect on you!
It is not that God will judge you, but that Satan is always looking for naive christians who are willing to obey him. God cannot stop you using freewill to give a home to His enemies. You haven't been defeated in battle, you have preferred the offerings of God's enemies to God himself. Adam did that if you recall.
I have met many christians whose lives have been blighted because they have given a home to occult stuff.
My wife was at a residential meeting somewhere years ago when a married couple asked for prayer. They were really struggling over health issues and spiritual oppression. As they prayed, one of the men gave out a simple vision that he had received for them. In the spirit, he had seen a picture of someone standing next to a pagan temple with its shadow casting over them. He said he didn't understand what it meant, but that it represented a demonic attack that had happened in the past.
The couple excused themselves for a few moments, and ran up to the room where they lodged, returning shortly with a photograph.
The photograph was of the two of them in Nepal standing near one of the many Hindu temples, with its shadow cast over them. The speaker had thought that the vision was a metaphor for something, not a real event.
They tore the photo up and commanded the demons that had obviously entered at that time to come out of them.
The oppression left immediately and following that, the health issue was resolved.
The church seems to be extremely naive when it comes to the works of Satan. Just becoming a christian does not stop Satan's evil works against God's people. We are called to war, only a fool would make his habitation with an agent of the enemy.
