You have to be sad in order to be happy?  God's economy often doesn't match the ideals of this world.  Jesus said, “Blessed are those who mourn, for they shall be comforted." in Matthew 5.  What does it mean to mourn?  In this passage we'll discover something deeper than simple pain.  This MOURN is the heaviest of all sad words in Scripture and it must certainly be part of the life of the happy believer.
