Do you think a god you can understand is worthy of the title?<quoted text>
Possibilities aren't all taken, are they? So how can God know for a fact the results of choices that we never make?
If you come to a fork in the road, you can only choose to go either right or left. You can't simultaneously do both. So if God knows you will go left, can you turn right instead? If yes, then you have free will but God is not omnipotent, if not then God is omnipotent but you don't have free will.
You can make arguments about whether God lives in linear time or not, but we certainly do live in linear time.
