Thematic Bible: What comes out of lust

What causes wars and contentions among you? Is it not the cravings which are ever at war within you for various pleasures? You covet things and yet cannot get them; you commit murder; you have passionate desires and yet cannot gain your end; you begin to fight and make war. You have not, because you do not pray; or you pray and yet do not receive, because you pray wrongly, your object being to waste what you get on some pleasure or another.
