Then how can we be "free beings"? Can you do anything *other* than what God has forever foreseen you doing?
If God has forever known that tomorrow at noon you'll do X, then when the time comes, you can *only* do X. You can't not do it, and you can't do Y instead. You can only do what God has foreseen.
If you make what you feel is a free choice, and God has always known what you'd choose, then the "freedom" is just an illusion, as you made the only decision you could have made. If you could make another choice instead, then the god isn't omniscient.
You keep talking about "God’s omniscience" and "God knows every choice you will freely make," but how do you even know that God even exists? Even if your argument about God knowing what choices you make not taking away your free will is true, it doesn't really mean anything if you can't prove the existence of the God you're talking about.
@Radical_EgoCom @graemearthur As far as we know "free will" isn't a thing as there is no physical mechanism that can deliver it.
The usual way out of this seems to be to say "in practice it's too complicated to calculate what someone will decide to do, so we might as well live our lives as if free will is actually a thing".
