[hmkpoker]

I don't think that your conclusion necessarily follows from the premises.

Let us say at moment A I choose action X. At moment B (later), I choose action Y. God observes both of these events more or less concurrently (that's probably the best way to put it), but doesn't necessarily control them. He would have to control these events for us to say that free will does not exist.

However, there is a limitation of sorts. God must have been able to see what would happen at moments A and B before he created the world and allowed it to happen. His intervention would at least have to be something like "ahhh, it looks like hmkpoker is going to do X at A and Y at B. Ok, I'll allow that." But even here, I think there is an element of choice, albeit counter-intuitive because it exists outside of time.
