If God is all knowing how can free will exist in humans to make their own decisions?
Could it be that God knows all possiblites of a situation such as an argument and what could lead from them and the humans through their actions thoughts or words pick the path? I’m not sure and would like to hear you’re ideas and thoughts
The standard reply is that God’s knowledge does not interfere with free will, does not “cause” the choice to be made. This simply won’t wash, because God is not a normal person, but has certain attributes in traditional theism.
It is not the case that God knows our choices as a result of our having made them. That would make Him (His knowledge) dependent on us and God is absolutely self-sufficient in all respects. Thus, His knowledge is not just temporally, but also logically prior to our choices; that’s why it’s typically called foreknowledge.
Now, whatever definition of free will one wants to use, most would admit there is no free will if there is not even the logical possibility of doing otherwise. Free will defenders often take God’s foreknowledge “off the table”, so to speak, and then claim person X has free will because there are logically possible worlds in which he does A and which he does not do A, everything being the same up to that point (not including God’s foreknowledge). However, God’s foreknowledge is ALSO part of the world, and there is no logically possible world with God’s foreknowledge of X doing A in which X does not do A. This should be enough to show the problem, but it will still be argued that God’s foreknowledge does not CAUSE the choice, even if it logically entails it (a choice being logically entailed is not “free will” to me, but different people have different ideas about what the “free” in “free will” means).
But, according to Divine simplicity God’s knowledge is IDENTICAL with His omnipotence, His power; His knowing and willing are one and the same thing, and nothing happens He does not will positively or at least permit, and His will IS the cause of everything (and don’t bring up sin; that is not a “thing” properly, ontologically speaking, but the “lack of a thing”); this will is prior to any choices of ours, and so the same objection stands; it is logically impossible to do otherwise than what God wills or permits, and when God wills something He is its cause.
The above argument stands whether you want to use a Thomist or Molinist framework, although the above was more Thomist in flavor. It’s the fashion nowadays to argue that saying that God’s foreknowledge and free will are incompatible is a “modal fallacy”. It is not. I am not arguing that God’s foreknowledge implies that our choices would be logically necessary in the absence of that foreknowledge - that would be a modal fallacy. I am arguing, in traditional theism, that with God’s foreknowledge our choices are logically entailed by something logically prior, though also itself contingent, and that does not sound much like “free” will to me.
