I had prayed asking God to show me if this was all valid for me in the twentieth century, and if it was, when and how to use it.
I found that I often became uneasy when I was around certain people, and asking God, I got the strong impression that what was wrong with them was of a demonic nature.
I prayed that if I ever came face-to-face with someone like that during a prayer-session that God would tell me what to do.
