How is the church supposed to deal with those who have mental illness?

Disclaimer: I’m not the expert on this, but this is my offering so far.  I already said I’ve failed at this.  At the end of the day we know the main answer is Jesus.  

Is it a demon?  Possession?  Chemical?  Psychological?  Spiritual?  What are the contributors to mental illness?  What is mental illness?   Does medication play a part?  We'll look at some biblical directives on answering the question and practical help and direction will be offered.
