James traces conflicts to passions at war within people (James 4:1). He also links unanswered asking to wrong motives—asking to spend it on pleasures (James 4:3).
In James 4:1–3, James traces community conflicts back to inner cravings that “go to war” inside people. Those desires spill outward into quarrels and even violence, yet still fail to deliver what is wanted. James adds that lack also comes from not asking God. These verses pick up the contrast just made between “wisdom” that produces peace and patterns that produce disorder (James 3:13–18). James turns from describing the two ways of life to confronting what he sees happening “among you” in the community.
James explains community conflicts by tracing them back to inward cravings. The “wars” and “fightings” are not presented as random personality clashes but as the outward spillover of “pleasures” (passions) that “war” inside people (explicit claim).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with James 4:1, then read the surrounding section so the answer stays connected to the passage's flow.
1Where do wars and fightings among you come from? Don`t they come from your pleasures that war in your members?
