To every Christian who is experiencing hardship in their life and in need of more joy.
James begins his letter with one of the most profoundly paradoxical statements in all of scripture: "Consider it all joy ... when you encounter various trials" (James 1:2). Or to paraphrase: "Be extremely happy when you face difficulty." The book of James is written to every Christian who is suffering under the weight of problems in their life; difficulties with family, job, finances, health, even death. James doesn't just tell us to be happy, but instead, shares with us a series of vital truths about God (and us) that reveal how God uses our difficulties to miraculously bring His joy, wisdom (what to know and do), and peace into the midst of whatever difficulty we happen to be facing.
