I Corinthians 10:19-21

What we are looking at here is a faith that motivates a people to sometimes a very zealous submission to their god. But it is a faith that any human being is capable of, as we can see, because obviously the true God is not involved in this faith that they have. If the true God were involved in it, these people would not be worshipping demons. But they are worshipping demons. They are doing it in ignorance. But they nonetheless believe very sincerely and devoutly. And in some cases are willing to go to great sacrifice in order to submit to what they believe the demands of their god is. But this is a human faith of which the human spirit is capable apart from the revelation of God.
