god has no free will

[JonDarbyXIII]

So God is omniscient because he knows everything that he knows. I could use that logic and make a similar claim that I know everything that is knowable. If I don't know it, then that knowledge doesn't exist (for me). Even if you claim that there is someone else that does know it, I don't know that knowledge indeed exists. Maybe the sky was destined to be blue whether God wanted it to be or not, but God didn't know that until he chose that.

The set of all that is knowable is not necessary the same as the set of knowing everything one knows. I know many things, but I do not know all that is knowable. You have made a straw man argument.

That's not straw man. You're saying that God only has to know what is knowable, and you are assuming that 'what is knowable' can be defined as 'what God knows.' You have not, however, shown that the knowledge can't exist outside of God. To the frog in the well, the well is the entire world. If there were a knowledge base outside your god, then he could still think he knew everything that was able to be known, but he would be just as limited as we are. My point is that I can make that claim (even if it implies arrogance). God makes that claim, and you call it divine.
