The Scriptures are very clear in what is behind every religious idol. In 1 Corinthians 10, it speaks about demons attaching themselves to these idols for the sole purpose to be invited into people’s homes to cause havoc.
14 Therefore, my dear friends, flee from idolatry… 19 What am I saying then? That food offered to idols is anything, or that an idol is anything? 20 No, but I do say that what they sacrifice, they sacrifice to demons and not to God. I do not want you to participate with demons! 21 You cannot drink the cup of the Lord and the cup of demons. You cannot share in the Lord’s table and the table of demons.1 Corinthians 10:14, 19-21 HCSB
