Culpability

If we had a friend who was about to commit some horrible crime, or perform an extremely dangerous, life threatening stunt, we would, with great effort, do all we could to warn him or try to stop him.  It would be reasonable and entirely expected of us.  No one would argue or label us a busybody for intervening.
This response is based upon our concern for their well being.  We are concerned that some sort of harm may befall them and this is a very reasonable concern, an expression of love.
But is our love limited to the mere physical?  What about being concerned over souls of our loved ones?  Are we or even should we be concerned when a loved one is poisoning/corrupting/damaging their heart and soul? 
Some of the real problem here is one of definitions.  It seems that most people believe in the existence of the soul, but it also seems that, practically speaking, few live as if the soul is real.  How is the soul defined?  Who can speak authoritatively on it?  Of course, you can guess to whom I will appeal in this regard.  We ought to, we should, we must, submit to the body of Christ for direction and definition for our hearts and souls.  We go to a doctor for our physical needs, why would we not do the same sort of thing for our souls?
Again, this is all about love.  We should act in love, not pride, not wanting to be "right",  not wanting to win an argument.  We have many problems here in America and the church needs to start acting like the church.  Let the world know us by our love.
