James 4:1-2

What leads to [the unending] quarrels and conflicts among you? Do they not come from your [hedonistic] desires that wage war in your [bodily] members [fighting for control over you]? You are jealous and covet [what others have] and your lust goes unfulfilled; so you murder. You are envious and cannot obtain [the object of your envy]; so you fight and battle. You do not have because you do not ask [it of God]. [1 John 3:15]
