Just believe

My favorite secular band is Journey.  They wrote a song 40 years ago that is still popular today and played in many sporting venues called "Don't stop believing."  There are times when it is hard to believe.  A loved one is sick, dying or already has died.  Finances are so messed up it is impossible to see any hope.  In Mark 5 a Synagogue leader named Jairus came to Jesus and asked him to help.  Things had to be pretty bad for a Hebrew religious leader to come to Jesus.  He wanted Jesus to heal his daughter.  Jesus told him just to believe.  How often is the answer to my problem my own faith?   I don't think God gives us enough to handle.  I think He gives us more so we will depend on Him.  If we could handle things, why would we need God?  So I wonder how my own faith determines what God does?
