"The Epistle of James..., the Book of James, or simply James, is one of the 22 epistles (didactic letters) in the New Testament," according to Wikipedia. "The author identifies himself as 'James, a servant of God and of the Lord Jesus Christ,' who is writing to 'the 12 tribes scattered abroad' (James 1:1).
"The epistle is traditionally attributed to James the Just, and the audience is generally considered to be Jewish Christians who were dispersed outside of Palestine due to persecution.
"Framed within an overall theme of patient perseverance during trials and temptations, James writes to encourage believers to live consistently with what they have learned in Christ.
"He desires for his readers to mature in their faith in Christ by living what they say they believe. James condemns various sins including pride, hypocrisy, favoritism, and slander. James encourages believers to humbly live Godly wisdom rather than worldly wisdom, and to pray in all situations."
