James 4 reminds us that selfish, prideful, covetous, and quarrelsome attitudes are derived from motivation by pleasure and desire for the ways of the world. James says that this "friendship with the world" is hatred toward God. In order to do avoid these behaviors, God calls us to continually humble ourselves before Him, submit to Him , and draw close to Him. Finally, we are reminded that we are only "a mist that appears for a little while and then vanishes". So we shouldn't boast about tomorrow but instead acknowledge God's omnipotence and condition our plans on His willing.
