James 4:1-3 NRSV
Those conflicts and disputes among you, where do they come from? Do they not come from your cravings that are at war within you? You want something and do not have it; so you commit murder. And you covet something and cannot obtain it; so you engage in disputes and conflicts. You do not have, because you do not ask. You ask and do not receive, because you ask wrongly, in order to spend what you get on your pleasures.
