Is the argument from freewill further supported by causal arguments

Question

The argument from freewill is a paradox that can be loosely described as, if God is omniscient or all knowing then God subject's, man , cannot have freewill as the 'fate' or actions of man have been predetermined by God. If Man has no freewill then God cannot have given man freewill

Is the argument from freewill, further supported by the casual argument of the kalam cosmological argument, and the causal indeterminacy of quantum mechanics.

Such that if the argument for God is a causal argument and the argument that freewill exists aslong as things are acausal. Is this also contradictory, or a Parodox, that you conclude God could not exist because of these circumstances?

Edit: For clarification of causal paradox.

If the universe is causal, then you can argue that God exists using the Kalam argument and God can give man free will. If the universe is not causal, then God cannot exist. However, the free will of man can exist and therefore God could have given man free will.

I dont know if the causal paradox I described is entirely Sound I just wanted to put it out there..

Answer 1

Omniscient is a word open to various nuances of interpretation. For example, some people will point out that it can mean knowing all there is to know, in which case what we might yet do in the exercise of our free may be considered outside the realm of what there is to know. Omniscient could also mean knowing everything one wishes to know. God might simply have decided that she wanted to leave us to our own devices, and didn't care about foreseeing the consequences of our actions. Or omniscience could mean knowing all possible outcomes, so perhaps God can foresee all of the choices we might make, and all of the possible consequences, without pinning us down to a particular path through the options. Or perhaps God has a way to foresee exactly what we will do even though it is not pre-determined, because to believe that it is foreseeable only if it is predetermined is a limitation of human reason that does not apply to God. The point of the foregoing is that there is more than enough wiggle room to evade any paradox if you are hell-bent on believing in God and free will, and to assume that logic can allow you to make sense of a concept as slippery as God is probably a mistake anyway.
