Sin is an evil controller of human being, this is why we need to get rid of it!

B.  Healing for the stain of sin.  Like a river overflowing its bank and running wild, sin tears our soul as it spills forth in its fury.  We need not only forgiveness, but healing for our spirits that have been victimized by sin.  Note the devastating hurt of sin in the life of the demonic child.  The Bible says, the evil spirit tare him.
