Silly Christianity - 2

Do you remember the first time you read Wild At Heart (if you're a woman, Captivating)?
One of the main things that the book (a good read, very helpful, even though I'm about to make fun of it) harps on is that the things that we desire, our deepest innermost longings, are a reflection of who God made us to be.
In Wild At Heart, that meant the reason men like to play wargames and be brutal is because God made us to be warriors. Women, if you read captivating, like to read Vogue or whatever it is that women read because God made them to be beautiful.
It's an interesting premise, and one that is getting more and more play in christian circles and books. I just read about it in a book for introverts (review forthcoming) - the idea that if we're not sure what to do, to listen deep down to what our desire is - that God planted that desire in our heart.
Does anyone have scriptures to back this whole premise up? Because it sounds silly to me. Here's the argument in different wording: "I should do what I want because that's what God wants me to."

Anyone else sensing a self serving christianity here? Maybe my desire to pickpocket is a God-planted desire. Or my desire to see the Red Wings destroy everyone else in the NHL is God-planted - because that desire is as real as any I've known.

It's a seriously silly question.
