The bible doesn't say anything about "free will." The pagan concept of free will not scriptural.
"Free will" means a moral agent can choose any action without coercion, restriction, or consequences from any other moral agent or moral authority. If there is coercion, restriction, or consequences imposed by another moral agent or authority, then our actions are not freely willed by our own desires, they are acted with limiting consideration given to those factors.
Scripturally, we get a limited choice, and we get that choice only by God's grace. God never said our actions were "free."
Moral determinism is clear in scripture. It's so clear that pagan philosophers levied scriptural determinism as a charge against Christianity. To counter that charge, Augustine invented a very narrow, limited kind of "free will" that is really a peculiar Christian concept. The limited choice that Christians call "free will" is not what anyone else calls free will.
Ironically, while ancient pagan philosophers touted "free will," Christians are the only people talking today about humans having free will. Secular philosophers have come to the conclusion that to some greater or lesser degree, there is no free will and that the universe is to some greater or lesser degree deterministic.
