What world, or reality, or dimension would this "free will" occupy (under this model)? I have been told with a straight face "no such thing as free will." Because that would then mean something which God would have to react to rather than initiate. Which would lessen God's sovereignty or so the theology goes. Is reacting to a creature's choice a possibility that is even available to God? Does God have the power to constrain His own sovereignty? The mind boggles.
Free will is defined as doing what is desired. They do what they desire which is ALWAYS sinful.
God never reacts because God wrote the script. Your typing your paragraph was part of the script, but it is also exactly what you desired to do.
