Written by Jesus' half brother Jacob, the book of James shares sage wisdom for all the churches and followers of Jesus. It's influenced by Proverbs and frequently quotes Jesus' Sermon on the Mount.
The introduction summarizes the words and themes found throughout the book, which is filled with short, challenging wisdom speeches that are full of metaphors and easily memorized one-liners.
While James doesn't teach new theology, it does challenge believers on how they should live. Topics covered include words, favoritism, love, wealth and hardship. When believers listen to and obey God's word, they love Him and others. Their actions match their words, and their lives are made whole, complete and perfect.
