James has addressed his readers as “brothers” and “dear brothers.” Now, in James 4:4–10, we come to the heart of the book with this dramatic accusation: “You adulteress people!” The division between believers is owing to a division within the members themselves, and this division is rooted in a division between the people and their Lord captured in this imagery of marital infidelity. This is a wake up call to repentance, to humbly return to the God who yearns jealously over his people. This is also a word concerning our God's jealousy for a loving, warm, and faithful relationship with his people, a relationship that begins with humility. What does that humility look like? James does more than tell us to humble ourselves, but he shows us what this humility looks like.
