Likewise, the omnipotence is important because without being able to CONTROL the consequences of your actions it can also be the case that you can't be held accountable.
But even with omnipotence and omniscience, if God creates a creature to exercise free will, God is not controlling the choices of that creature. That's the definition of free will.
What is actually the primary issue is a choice that was made, and an action taken. God exerted his free will to create the universe in a specific way when he was presumably free to make it in other ways if he so chose. Those other ways might have been worse, or better, or just different and that's not relevant. What is relevant is that the design of the universe was a choice, and that design included - before the actual act of creation - all of the choices that would be made in the universe.
This is an assumption I'm not comfortable with. Does God have free will? Did God choose among alternative worlds in creating the world as He did? I honestly don't know. So anything that requires God's free will choice as a premise is something I'm not ready to accept at face value.
It's not that he knew them, it's that he CHOSE them. God - especially if you believe that he is outside of time - made the entire universe from start to finish in a single choice. It was a deliberate act that knowingly involved not just every physical object but every event in the entire universe.
Since he already made that choice, and all of my choices are included within it, it is god's will being done by my actions and not my own.
Again, I disagree -- although it was God's will that a free moral agent be created, and although God knew what choices the free moral agent would make, this does
not negate the free agency behind those choices. Nor do you seem to be presenting a reason to believe that the free agency is negated, other than the fact that a knowing and voluntary action by God was necessary for that choice to ever be possible.
As an extreme example, let's say that I built a shooting range, bought a gun, loaded the gun, stood you in front of the target, put the gun in your hand, lined up your sights on the target, and put your finger on the trigger. Then I stand back.
You then pull the trigger.
Could I be said to be a necessary cause of that target getting shot? Of course. Did I make free will choices that resulted in that target getting shot? Sure. But the fact that you had a choice as to whether or not to pull the trigger,
regardless of whether I knew that you would pull the trigger or not, means that your free will choice was an intervening cause in that target being shot. None of my facilitative steps remove your choice. Your choice is still there, and it's a real choice.
Something I don't think I've said before now -- I do think there are hypothetical circumstances where humans
don't really have free will choices, and in fact I think it takes a particularly detailed design for God to live up to His assurances to us that
we will never be tempted past the point where we have the capacity to resist. But that's the guarantee we have -- that although in practice we all sin at some point, the sin is always an individual choice, not some sort of entrapment. Moral situations are carefully constructed in our lives to always permit a morally right solution that is actually available for use.
I don't see this as any sort of iron-clad refutation of your points; as I said before, I think your position is reasonable. But I hope you feel I've addressed your points.
