Prediction is not necessarily prophecy and a prediction does not always come true.
Lets say the bible has a prophecy that says purple dawn will walk in front of a bus on august the 20tieth and die.
If you do walk in front of a bus and die then that is strong evidence of no free will because you would always make the same choice free will would only be an illusion a belief that you actually can choose what to do, but the choice is always the same as the one predicted.
But if you would not walk in front of the bus then that would be evidence to support that there is no such thing as prophecy and that you have the free will to chose what to do all the time.
To put it more in context with the bible at the end of times after the good guys have been raptured the rest follows Satan to wage the last battle at Armageddon, do these humans that where left behind the atheists who finally got some evidence that god exists dont have a choice to say no belzebos you go and fight your own battle im staying behind, the just blindly follow the guy in to battle knowing they will loose.
