And God could have chosen not to create anything, so what? I don't understand the point in some 'metaphysical hypothetical,' something that could have been.
The OP indicates the argument is entirely based on considering hypotheticals: "If He did", "if we believe in all good God", "if God does not intercede" ...
So consider the hypothetical that's constructed. The assertion for this hypothetical is that God is somehow not responsible. But it can't escape the fact that God is entirely responsible for each event in a creation He has built in infinite knowledge and complete detail. He knows. He did so anyway. The fact that God created everything removes omnipotence from being a factor. Were we children, we could confidently claim, "Well He started it!" And we'd be right.
There's no backlash here. God will put all evil to right. That demonstrates that God is just. However, determinism doesn't mean God's responsible for evil. That's already established. God is still extensively responsible for everything He's created, determinism or not. Arguing otherwise is a false dilemma argument combined with a false cause argument.
Right, that would more than likely be the hyper Calvinist. Either way if predestination is centered around divine intervention, and God predestines more than half or whatever of humanity to hell, He directly intervenes to damn them. That is my basic premise. God's motivation may not be to damn them but I am mean damn, even Calvinists believe God created man for destruction, as to glorify His wrath. And they even say the atonement was limited to the elect and was not intended for the rest of man.
Adding more errors in representing Calvinism would generally make this discussion less and less about predestination, and more and more about misrepresentation.
Again I don't think this is much of a point. I agree God knows everything, but so what if He could have done this or could have done that? It's not what actually happened, and that should be the point of discussion.
The point is this: that God has the capability to make everything right, to do everything right, for everything to be right.
His sense of justice would lead Him to actually do everything right.
He created this world and hasn't lost control of it.
So He actually has the knowledge and power that the OP asserts He doesn't.
The presentation of the OP essentially says God is incapable of preventing evil from entering His world, and compelled to make it in such a way that evil does enter. To absolve God would require God is not fully knowledgeable, because as people are presuming here, the universe is filled with evil that wouldn't happen if God didn't create. So "not create" is better than "create".
The contradiction is palpable: God did create.
Tracing back to the error in such an argument: only two possible errors exist. Either God isn't good; or our assumptions are not accurate.
Were the assumptions and possible solutions traced back, we'd get to the point of noticing either our ideas about God
or our ideas about creation are wrong. I think we've reviewed our ideas about God, but again, open theists tend to say that's the issue. But on the other hand, Calvinists say our ideas are wrong about creation.
