Do cancelled prophecies automatically imply falsehood? If I remember correctly Nineveh’s prophesied overturning was averted/relented BECAUSE they repented. So did God initially intend that or not? I however agree that many specifics cannot be known by man, but I think we refer to generalities more in the subject of Open Theism. On the subject of False Prophets, they are also allowed by God, to speak true descriptions, of both present and future, but does that make them True since they speak truth at that moment? (Deuteronomy 13:1-3). How about “pray that your flight may not be on the Sabbath or winter”? Now if every single detail of Future History is settled by God entirely beforehand, unilaterally, without recourse to His creatures, what is the point of saying that God has 2 wills? Wouldn’t that make what He does/approves and allows/tolerates absolutely identical?
