John McCormick on the Open Theism Facebook page:
(1) Rather than saying that God chose to leave the future open, I think it would be better to say that He did not create a future. In other words, God created only the “present”, and no past or future exist–not even in some meta-time that only God can see.
This is called Presentism, and it is compatible both with Scripture and physics.
Indeterminism is a central feature of quantum physics. My own study of time and physics indicates that there is no such thing as “time”, but only a constantly-changing “now”. I have personally verified this with physicists, including one of the leading physicists in time research.
Scripture supports Presentism through as many as 11,000 verses that indicate that there are things God does not know. (I’d be happy to supply you with a representative sample of those verses, or all of them if you want.) Yet we know for other reasons that God necessarily must have all power and all knowledge (many Open Theists would disagree…but they are all dorks…just kidding), so if it appears that He does not know a thing, then it means that things simply cannot be known–like a square circle, which is nonsense.
