I agree about man being able to choose, except for the term itself, free will.
Real freedom happens when man operates under God.
Take any addiction, and you see what I mean. A person in any habitual sin is enslaved and controlled by sin, and not free.
So if we use the term "free will" it might shift us away from the biblical paradigm unintendedly.
God looses the prisoners, breaks prison walls, etc.
I stopped using the term "free will" (thank you Magenta!) and call that choice possibility "man's will (or choice)" and am open to hear a yet better term if there is any...
