Could God's creation be like His omniscience?

[Neo-Scholastic]

I think SteveII takes a more Arminian position (see Wesley's position in the above graphic) but he can correct me if I'm wrong. I have some thoughts about it based on my own philosophical speculations about the nature of time (still very rough); however, I think it is bad practice to read Scripture through a philosophical position rather than allowing the text to speak for itself. In this case Scripture seems to be indeterminate on the matter. There may be a way to resolve the dilemma of God's Sovereignty with Man's responsibility, but I really haven't had much luck cracking that nut. On the one hand, it seems to me that an omniscient being could only know that which it is possible to know. If the future does not yet exist then it is impossible to have knowledge of it. On the other hand, couldn't God extrapolate from current conditions? Only if the physical universe is causally closed. I would not be willing to concede that. There is an intermediate position along the lines that God's purposes are fore-ordained but the paths to achieving those purposes are not. It would be like a captain constantly adjusting the sails in response to changes in the wind. As such people enjoy freedom within certain parameters, but not to the extent that it could thwart God's ultimate goal.
