a Calvinist does not believe God is stone idol but that is what open theist say Calvinist believe every time
Not every time but when we do it is not only based upon but almost always explained that a God that cannot change in any way whatsoever is describing a stone idol not a living, dynamic, loving God who becomes a human man so as to die and then rise from the dead.
In other words, it is not an intentional, made up out of whole clothe, total straw man argument where we actually are trying to make people believe that Calvinists ACTUALLY have idols made of rock in the living rooms and at their churches.
What you are doing is something entirely different. You actually want people to believe that open theism teaches that God has no idea what anyone is going to do and that it's little more than a comic coin toss whether His prophecies will come to pass or not while in reality open theists actually believe the opposite and take the bible to mean precisely what it says that calls the end from the beginning.
do open theist say God is guessing, of course not , but it is the natural conclusion of what open theist teach
No, it absolutely is not!
When you make plans to go on vacation and you book reservations on a cruse ship for next June and then in February the ship you thought you were going to Belize on ends up catching fire and sinking to the bottom of the Gulf of Mexico, is it in ANY WAY accurate to say that you had been guessing about which ship you were going to be taking the cruise on?
Now that's an example from a human perspective but that only strengthens the argument because we humans don't have access to 1% of the information that God has nor do we have the power to protect cruise ships from accidental fires and sinking the way God could if He chose to do so and yet it STILL is not accurate to call what we were doing "guessing". That just isn't what it means to guess!
What's more is that YOU KNOW that this isn't what it means to guess and you make the accusation anyway and that's why it's a lie.
not mischaracterization but natural conclusion
Liar
sooo not guessing but then you say could be guessing .
No! The potential for circumstances to change and therefore your intended plan of action to change with it is not at all what it means to be guessing and you know it!
Saying it doesn't make it so!
God is prophesying the punishment and the unrepentance
No, He isn't! He says IF not WHEN. IF the repent then so will He. IF they do not repent then the punishment will commence as prophesied.
Jonah prophesied that Nineveh would be destroyed in forty days. The entire prophesy is I think something like five words in the original language. There was no mention of repentance to mention of potential reprieve. God did NOT prophesy both the punishment and the repentance as you claim but only the destruction of Nineveh in forty days. Forty-one days later, Nineveh is still standing and thriving and in better shape than ever before because God did not do that which He said He would do in response to Nineveh's repentance.
Jonah 3:
10 Then God saw their works, that they turned from their evil way; and God repented from the disaster that He had said He would bring upon them, and He did not do it.
and you an open theist say God is guessing that he may or may not punish & they may or may not repent.
You are a liar!
I have never said any such thing. God absolutely was not guessing and totally would have completely destroyed Nineveh just as He said He would do but didn't because and only because they repented which even Jonah fully expected them to do which is why he refused to go in the first place.
Rev 16:8 And the fourth angel poured out his vial onto the sun. And it was given to him to burn men with fire.
Rev 16:9 And men were burned with great heat. And they blasphemed the name of God, He having authority over these plagues. And they did not repent in order to give Him glory.
This prophecy is under the same sort of conditions as the Nineveh prophecy. If Israel repents then so will God.
The entire book of Jonah is dedicated to telling the story of but one of several biblical prophesies that did not come to pass. You say you reject Calvinism and Open Theism so that leaves little else except some form of Arminianism but when it comes to prophesy and God's foreknowledge, there's not a dimes worth of difference between them and the Calvinists, so how do you explain the prophesies in the bible that did not come to pass?
