The Book of James is commonly thought to have been written by Jesus’ half-brother, James. Many believe he was writing to Jewish Christians. James wrote this letter to correct any misunderstandings about the nature of faith. James began with a greeting, then quickly transitioned into an encouragement to stay faithful through trials and sufferings. Afterward, he wasted no time moving straight into his teaching on faith. James agreed with the writer of Romans, who confirms that faith comes from hearing the Word of God (Romans 10:17).
