I know that I'm not DVT Dave but I have a feeling that some of my answers will be somewhat different that Dave's and so I though it would be interesting for me to offer my answers to Lonster's questions as well.
Dave, Please do not let this post prevent you from responding directly with your own post. I'd love to find out just how different our answers will be.
Can we discuss what is lost and what is gained from each perspective?
OV would state God could not know, specifically by His own volition because He has the power to know. If I'm understanding correctly.
A nonOV position would state that God must know for He has Foreknowledge (some in differing perspectives would say exhaustive). Furthermore, He could not be competent if there were too many contingencies (this or a variance is leveled often toward the OV position).
So one side suggests an impossibility and claim that nonOV has God in a tyrannical position. The other, that God is much smaller and unable.
What I'd like to hear is exactly what is lost and what is gained in the respective viewpoints.
Here are a few leading questions but expound anything that is pertinent.
-If God does not know future exhaustively, how much does He know? Is it limited to determinism?
God is able to know all that is logically knowable but only actually knows that portion of the knowable information that He wants to know. As for the future God knows the portion of the future which He has decided to unilaterally bring to pass by His own power. The glorification of the Body of Christ and the creation of a new Heaven and new Earth of a couple of examples.
I don't think I understand your question about "Is it limited to determinism?"
-If God made Adam with a faulty sin valve, did He know about it? Was it faulty?
"Was it faulty?" is the key question here. No! It was not faulty.
This question I think leads from a faulty understanding of why God created man in the first place. The Calvinist thinks that God does everything to glorify Himself and for only that reason and while all things that God does do bring Him glory, that isn't why He does them. God is not selfish but rather loving. God created man so that He might have a relationship with him. God wanted Adam to love Him and the only way that is possible is for God to create Adam with the capacity to reject Him. This is the premise of the book,
The God Who Risks by John Sanders. God very much wanted Adam not to sin and Adam could have done just that. God, of course wasn't unprepared for either circumstance.
How is God impinged or expunged?
This question makes very little sense to me Lonster.
Impinged? Do you mean affected? If so, God is affected by nearly everything we do! Prayer is the obvious answer but love, hate, righteousness, sin; all these things and anything that would be described by them would affect God.
Expunged? Do you mean removed, exhausted, deleted? I don't get it. God cannot be expunged.
-What was necessary for man to have choice? What factor had to be part of Adam's makeup for this to work?
For what to work? If I understand your question, which I don't know that I do, we may not know the answer to this question.
What we do know is that without choice morality is meaningless. If you cannot choose, you simply cannot do rightly nor sin. So the only answer I know how to give you is that in order for Adam to have a choice he had to have been given not only options to choose from but the ability to pick from those options by an act of his own will. As for how that works and just what part of Adam's make up causes it to work, I think is impossible for us to know. We haven't been told.
-How is God's omnicompetence accomplished if He does not know outcomes?
It would not be accomplished if He did! Competence has to do with skill and the ability to anticipate. Firm knowledge of the outcome requires neither. If God exhaustively knows the future, competence is just not a word that would apply.
-How do you handle difficult passages like Revelation with interaction if the future is impossible to travel to?
This might sound like a pat answer but honestly, the answer is, by not reading our theology into the passages and taking more from them than they actually say.
If it was not future, is it merely predictive or absolute?
How can you know?
It's predictive. We know because the contrary is a rational impossibility. The future does not exist. No one, including God, can go to a place that does not exist, nor can God send John there. We can further know because such predictive prophecies have been made by God before, some of which did not come to pass per the warning given in Jeremiah 18. Much of Revelation is no different. The book has to do with Israel, its purging and its being given a kingdom. If the world repents, which I agree is quite unlikely, then God will not bring the disaster which He said He would bring. That's what Jeremiah 18 explicitly states.
I frankly don't understand how the Calvinist worldview can withstand a single reading of Jeremiah 18.
-God promises in glory, that all tears and sorrow will be eliminated. We understand that sin will be erradicated also. How is this accomplished if we really do have freewill? Do we lose it at Heaven's doorstep?
This question has been brought up a few times even within Open View circles. The answer is, we don't know. My response is usually to say that we will resist doing evil by the same mechanism that God Himself does. God has existed for an eternity without ever having done anything that was not in the best interest of others and has done so while being free and able to do otherwise. We will do the same and do it by whatever means God does it, presumably by the power of God Himself. Beyond that, any answer to this question would be speculation.
I could post more, but I just want to get to a treatise on the OV that is a bit more cogent than just a mere thread post if possible.
I recommend reading
Is Openness Christian theism?
and then pretty much anything on
THIS web page.
