When I was in college, I studied a lot or religion and philosophy. I will never forget the day -in my senior year--when one of the students stood up and started talking on and on. (I think we were discussing William James at the time.) The professor asked him to take his seat, and the student refused. I know God, he said. You have to listen to me. God is telling me what to say-do-think . . .
The professor put his arm around him and led him out the room. The student, I later learned, had to spend some time in a mental institution. I asked about this event later, and the professor laughed. He said it's not an uncommon event to have someone become deluded in this way. To think that God is telling him what to do or say. That he knows what God wants and means, that you don't. It happens to preachers and politicians, too. To those who want the microphone most.
