I've been reading Sara's blogs for a couple of years now. Recently, she started the James Challenge. You can check out more at her site, and specifically this post. I guarantee you will be blessed if you join in on the challenge (the verse purse is so cute)!
The book of James is such a good tool for Christians. I like how it focuses on the joy we can have through Jesus. John Piper has a great article titled:
I pray that you will find joy in everything you do, through Him.
