James 4:2-4

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] You ask [God for something] and do not receive it, because you ask with wrong motives [out of selfishness or with an unrighteous agenda], so that [when you get what you want] you may spend it on your [hedonistic] desires. You adulteresses [disloyal sinners—flirting with the world and breaking your vow to God]! Do you not know that being the world’s friend [that is, loving the things of the world] is being God’s enemy? So whoever chooses to be a friend of the world makes himself an enemy of God.
