Attributed to the brother of Y'shua, James focuses on practical application of the Word of God to a believer's life. In chapter 1, he starts with a paraphrase of Proverbs 2 - how to seek God's wisdom - and finishes with an admonition that the believer should put God's Word into practice or risk becoming futile in his religion.
James writes of unrighteous partiality based on perceived wealth. In God's eyes, a faithful poor person is preferred over an unrighteous wealthy one. He then goes on to speak of the proper attitude toward works., basically saying that a profession of faith that does not translate into good works is in vain.
The tongue is both hidden and visible. It serves as the gateway for the things of the heart to be revealed. When governed by wisdom, it promotes societal well being. When the heart is wicked or foolish, it can cause great harm.
James talks about pride in the context of wealth, slander and boasting. Those who live for their wealth will find no peace and that wealth finally desserts them. Those who slander others will find themselves shunned. Those who boast of their plans may find that God has other plans for them.
Writing to Hebrews, James does not present a balanced approach to wealth. Rather he simply condemns its unjust accumulation and use. Since God uses wealth to motivate us, Proverbs presents both sides of wealth. James' advice on healing mirrors that of the Great Commission.
