God's knowing the future forces no choice.
It seems to me like Schrodinger's cat. If you don't ask God about your personal future, he will correctly forsee it. If you were somehow able to question it, and he respond to you, you would obviously change course, just to prove God wrong, though you cannot, because God is immutable. At the end of the day, a paradox would result, and you would end up doing the very thing you set out not to do.
