Here is my thought.
Matthew 4 verse 8 Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. 9“All this I will give you,” he said, “if you will bow down and worship me.”
Jesus always replied to the devil with scripture. 10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’ ”
I think the satanists fell for the lie and are in so deep they may never see that God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
I pity them.
