Depression

There are four roots to depression. 

1.  Physical (tired).  Solution: rest.

2.  Moral (guilt).  Solution: forgiveness.

3.  Psychological (chemical imbalance).  Solution: love.

4.  Spiritual (demon root).  Solution: Jesus.

In Mark 5:1-20, Jesus heals a man possessed by a Legion of demons.  A legion would have consisted anywhere between 3,500 to 8.000 individuals.  Jesus banishes the legion of demons with the same effort of banishing one demon, with His command.  This is because JEsus is the highest name, the highest power.  He is God.
