I think if God's ability to know the future is limited to only knowing what He causes to come about, then he is not omniscient at all, he is merely omnipotent and his omnipotency has structural limitations and boundaries.
If what you say about "Cod" is true...then something seems really fishy to me.
I'm gonna let the questions in my mind float and I'll tackle them later. I don't intend to bait you with this reply, but I am hoping you'll get hooked into the conversation. I could net some good material for later, so I don't want to let this big one get away. Perhaps you'll get my drift and stay on line.
Seriously: What structural limitations and boundaries are you think of?
Also Seriously: If God is INDEPENDENTLY prescient, then He could not possibly have EVER not known the future, even when He was planning.
Are we to assume He refused to consult what He already knew when He laid His plans and made His decisions?
That's no different than those groups who get around the foreknowledge problem by saying "he refuses to look." How can he not know what he refuses to look at?
How can he not know the results even as he plans?
