Is there any room for free will?

I would love to believe that we have all posses’ free will. Furthermore, I venture to speculate that many of you would love believe the same thing. After all, if we are living a life that was determined before we drew our first breath what is the point? Why live in this grief stricken world where man strikes out against man and young girls are sold for sex if we have no control over ourselves and by extension over anything else? If the horror is true and free will is a non-existent we are effectively puppets on strings, every movement manipulated.
Many of us are psychology majors and from intro have heard of the nature/nurture debate. A nature stance is similar to Thomas Hobbes belief that humans are machines. We are born with a certain blue print that makes us who we are in virtually every respect as a machine is constructed with a blue print that determines its function. A nurture stance is similar to John Locke and his “blank slate” where we are born into this world with a blank blue print and our experience writes on it and determines what we will become. Which of these two do I believe in more strongly? Well, both and neither.
On the nature side, studies have shown that the temperament of an infant can be observed and that observed temperament is consistent over time, suggesting our personality to be innate. Moreover, when one looks at twin studies the data is more shocking displaying that prediction of countless aspects of one twin can be made accurately by simply looking at the other twin. Even more shocking to the Christian, Dr. McAnulty mentioned in class that susceptibility to believe in God can be linked to biological functioning in the brain!! How crazy is that!! (I would like to see that study by the way Dr. McAnulty) On the nurture side, we can look at studies like those that Bandura performed where children learn by mirroring other children; the experience determining what was learned. We can also look at the familiar Pavlov experiments of conditioning. It is then, as you have heard before, a combination of nature and nurture that makes an individual who he or she is.
My point is not to teach you what you already know, but to ask a question. If biological make-up is one part of the puzzle and experience the other part, is there any room left for free will? Every person is born with a particular blueprint (nature) and then experience works within that blueprint (nurture) to create the person. Therefore, the person seems to have no choice in either the blueprint that was provided or the scribbles made on it by experience. The biggest reason that this debates weighs heavily upon me is because I believe in God, but I also believe that every human is a product of his or her environment within the context of his or her biological make-up. We certainly cannot choose our biology and while, to some extent, we can choose our environment our biology almost determines how we will act within that environmental context that we have chosen (to go even further, our biology may even make the choice of what we choose to be our environment.)
In Light of all this, it seems as though I do not believe in free will, but I actually do not because of logic, but because of desire; I want to believe in free will. Most of this has to do with the unfortunate reality of the hell. I would love to pretend that there is no such place and I wish more than anything that everyone would spend eternity with Christ, but scripture makes it obvious that I pretend and wish in vain. Christ would not tell us to enter through the narrow gate if there was no wide gate that leads to destruction that many enter through. In the end, I choose to believe in free will because I refuse to believe in a God that creates people to go to hell. God creates a man with the biological make-up that is not favorable to believing in Him. Then God allows that man to be put into an environment that is also unfavorable to believing in Him. However, God still sends that man to hell because the man never believed (How could he?). If God creates men or woman like this, I do not want God to be my God. God cannot be a good God if this is true. Therefore, while I believe that nature and nurture leave little room for free will, if any, I make room because a shear unwillingness to believe that God would send people to hell simply because they were products of a crappy set of genes and an equally crappy environment.
I thought this music video is funny in reference to “puppets on strings” from my first paragraph: http://www.youtube.com/watch?v=-ZfsmLP2T3Q
