He asks God for it. He finds a nice sporty red one. He applies for a loan and gets turned down because he doesn't make enough money. So he asks God for a raise, but his boss says no. Bill feels angry with his boss, the bank, and with himself because his goal of getting that car has been blocked.
Disappointment is appropriate.
But Bill's anger indicates that the car meant more to him than it should have. The body's demand for rest, the longing for love, the desire for respect, and the hunger to make a difference are indeed legitimate. These are basic longings of the human body and heart. They cry out for satisfaction. But in an imperfect world of self-centered people, even those legitimate desires will never be fully satisfied by the best of relationships or by the best of circumstances.
