This is one of my favorite stories.
I know too many people like this guy. In fact I know a couple who make him look like a boy scout.
Mark 5:1-5 (NIV)
They went across the lake to the region of the Gerasenes.  When Jesus got out of the boat, a man with an evil spirit came from the tombs to meet him.  This man lived in the tombs, and no one could bind him any more, not even with a chain.  For he had often been chained hand and foot, but he tore the chains apart and broke the irons on his feet. No one was strong enough to subdue him.  Night and day among the tombs and in the hills he would cry out and cut himself with stones.
Read his symptoms carefully–loud, violent, scary, self-harming. Just like the rest of us, this man has a story, and not a fun one. Abused and neglected? Maybe? Into violent games? Maybe? Dangerous to others? Definitely.
No hope. No national mental health initiatives to save him.
There are 2000 reasons why he has chains and lives in the graveyard.
Now imagine you find out he has a little baby with him out there…
Would you worry? Would you call for help? Send him cloth diapers? Try to intervene?
What would you do for the child?
