Is this stuff real or crazy?

The other day, I was talking with a friend from East Asia and he told me a story that was a lot like this one:

“Be quiet!” said Jesus sternly. “Come out of him!”  The impure spirit shook the man violently and came out of him with a shriek.  The impure spirit shook the man violently and came out of him with a shriek.  The people were all so amazed that they asked each other, “What is this? A new teaching—and with authority! He even gives orders to impure spirits and they obey him.”  Mark 1:25-27 (NIV)

This friend’s story dealt with praying over someone and the person acted as if they had an impure spirit in them.  The person talked about bad things they had done and convulsed several times as they prayed over him.  I did not know how to ask him what I wanted to, but I tried.  I wanted to ask,”Do you think that this is crazy or real?’  I wanted to see what he thought on the matter.  I ended up asking him: “What did you think when this happened?”  He said: “I expect anything to happen so nothing surprises me!”

Do you think this stuff is crazy?  Do you have enough faith that you are willing to expect anything and take action on it?  Do things surprise you?  Do you keep an open mind guided by the Word so that God can use you?
