Intercessory prayer is pointless

[Abaddon_ire]

But your god knew that you would, you had no choice in the matter.

That does not make sense. I know my wife will choose chocolate ice cream over butter pecan every time. Does that mean she is not exercising free will? God derives his knowledge of what we will do given every actual and counterfactual circumstance because of his perfect predictive knowledge.

Your wife has no choice at all. god already knows.
