[Angrist]

I believe in a free will.

Sure, God can know and predict everything, but he doesn't determine it.
Like if a wheatherman gives you a forecast, does that mean he controls the wheather?

God tells us in the bible to choose.
Deuteronomy 30:19,20:
"I do take the heavens and the earth as witnesses against you today, that I have put life and death before you, the blessing and the malediction; and you must choose life in order that you may keep alive, you and your offspring, by loving Jehovah your God, by listening to his voice and by sticking to him; for he is your life and the length of your days, that you may dwell upon the ground that Jehovah swore to your forefathers Abraham, Isaac and Jacob to give to them."
