JAM:4:1-3
What is the cause of wars and fighting among you? is it not in your desires which are at war in your bodies?You are burning with desire, and have not your desire, so you put men to death; you are full of envy, and you are not able to get your desire, so you are fighting and making war; you have not your desire, because you do not make request for it.You make your request but you do not get it, because your request has been wrongly made, desiring the thing only so that you may make use of it for your pleasure.
