Free from whom or what is it then?
Within the confines of science, and outside the consideration of religion, philosophy, or faith, free will simply refers to the limits of determinism. i.e., is it possible to have enough information about the initial state of someone's life to perfectly predict all of their actions? At the moment, quantum mechanics says no, and so science says we have free will.
However, it's not a black-and-white, on-or-off thing either. Psychology and sociology can both make predictions about a person's life based on specifics of the person's initial state, and as genetics and biological sciences continue to touch borders with psychology, we find more and more that there are physical forces which influence the way people behave.
So, to what extent is there free will? If someone is born with the genetic traits for schizophrenia -- pre-determined by their parents, and their parents before them, and so on -- then just how much free will does that person have?
The question of determinism has nothing necessarily to do with religion.
