The brain

I watched "Concussion" last night.  This is a true story about Dr. Bennet Omalu, a pathologist from Pittsburgh who discovered CTE, chronic traumatic encephalopathy.  Basically, he discovered the terrible trauma put upon the brain by playing multiple years of aggressive football.  The movie painted a pretty grim picture of just how dangerous a game football is.
As I pondered the movie, it occurred to me how well built our brains actually are.  I began thinking about the multiple situations involving the brain, involving disease, disorder or trauma.  In every situation, that I can think of, anytime someone has these issues, the psychological results are always negative.  The "voices" that people hear are always negative or confusing.  They never hear voices that tell them to do good things, to help people, or things that build them up and encourage them.
This is curious and cannot be coincidental.  I believe that when God designed our brains, he built them in such a way that they have defenses built in. When disease, disorder or trauma occurs, we lose those defenses, in one way or another, and become susceptible to outside influence.  Essentially, these things open us up to demonic attack.
These are preliminary thoughts.  We'll see if this develops any further.
