Who is this James?  Why is he a servant?  Who are the 12 tribes?  Why do we care about this letter? 

This first section lays out the answers and sets the stage for understanding this epistle and applying it to our lives.

What is joy?  Why should I have it?  How do I get it?  What difference does it make?

Living in light of the work of Christ, should produce certain things in us.  In this section, James lays out some of that produce.

What is wisdom?  Why do I need it?  Why will God give it to me if I ask?  

Living wisely in the world, as James has exhorted the people to do, requires Godliness and wisdom.  James grounds his teaching in God, as the only wise foundation.
