Oh, this guy (Larson) again. I remember him years ago on TBN, always relegated to horrible time slots (Tuesday mornings at 4am Eastern, for example). If you check his home page, you’ll see that he sells (for a $5 Paypal charge) a 30-question self-test to see if you have a demon in you. That should answer all questions right there.
Thanks. You told me what I need to know.
