Why do you fight and argue among yourselves? Isn't it because of your sinful longings? They fight inside you.
You want something, but you can't get it. You kill and want what others have. But you can't have what you want. You argue and fight. You don't have what you want, because you don't ask God.
When you do ask for something, you don't receive it. Why? Because you ask for the wrong reason. You want to spend your money on your sinful pleasures.
