Bible scholars generally agree that James, Jesus oldest brother, authored this letter.
The book opens with positive Christian encouragement to embrace trials and tribulations as opportunities for growth.
However, James does state that temptation does not come from God 1:13-15 "When tempted, no one should say, 'God is tempting me.' For God cannot be tempted by evil, nor does he tempt anyone; but each one is tempted when, by his own evil desire, he is dragged away and enticed. Then, after desire has conceived, it gives birth to sin; and sin, when it is full-grown gives birth to death."
James advises in 1:19 "My dear brothers, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, for man's anger does not bring about the righteous life that God desires."
James challenges believers to put their faith to work to assist others. James encourages a righteous heart when approaching the Lord with requests, 4:3 "When you ask, you do not receive, because you ask, you do not receive, because you ask with wrong motives, that you may spend what you get on your pleasures.
1:19 reminds believers to take care of other believers "My brothers, if one of you should wander from the truth and one should bring him back, remember this: Whoever turns a sinner from the error of his way will save him from death and cover over a multitude of sins."
