Serious Prayer?

This little story is funny, but it has a serious message.

A man was driving down the street in a sweat because he had an important meeting and couldn't find a parking place. Looking up toward heaven, he said "Lord, take pity on me. If you find me a parking place I will go to church every Sunday for the rest of my life and give up drinking."

Miraculously, a parking place appeared.

The man looked up again and said "Never mind. I found one."
