I listened to an excellent talk on envy today. I wonder if this is the big sin of our age. I want stuff, not so much for the sake of the stuff, but for the sake of having as much or more than others. Joseph's brothers didn't feel the need for a colourful coat until their brother got one. I'm perfectly content with my house until I visit my wealthy friends' houses. I am satisfied with my 3 kids until I hear that a friend is expecting her fourth. [Then I have to remind myself that I don't want another and to feel that twinge of unease (I'm no longer winning!) is silly and wrong.]
It really is a good talk. Put it on while you're washing the dishes or doing the ironing.
