What is the source of quarrels among you?  Is the source not your pleasures that wage war in your body parts? You lust and do not have, so you commit murder. And you are envious and can not obtain, so you fight and quarrel. You do not have because you do not ask, You ask and do not have because you ask with the wrong motives, so that you may spend what you request on your pleasures.

You adulteresses, do you not know that friendship with the world is hostility toward God? Therefore whoever wants to be a friend of the world makes himself an enemy of God. Or do you think that the Scripture speaks to no purpose, 'He jealously desires the spirit who he has made to dwell in us'? But he gives us a great grace. Therefore it says, 'God is opposed to the proud, but gives grace to the humble. (James 4:1-6, NASB)
