1. Our conscience tells us we are responsible, but is that explaining how we can be responsible without "uncaused" free will? Not really, is it? It is just saying we are responsible, but it gives no explanation how it is possible without "uncaused" free will.
It seems to me you focus more on if God can hold us responsible, rather than if we logically are responsible. God could hold me responsible for robbing a bank even I never commited that crime. But is that logical or just? The question is not if God can hold us responsible, but whether we are logically responsible for the choices we make.
My argument was that there are ways to show that it cannot be said that God does not, or would not, or that it would not be just for him to, cause people the circumstances (causes) in which they make choices according to their inclinations and influences, yet hold them responsible for their choices:
Thus: If God says they are responsible, and if God says that he causes all things, there is no need to say otherwise for either one of those; no need to reinterpret Scripture, because, (at the least), #'s 1,2,3,4.
God makes no statement that he will hold you responsible for holding up a bank you did not hold up. The example does not serve your point. But God
does make a statement that he imputes the guilt of Adam's sin onto us. Since we know that to be so, and we also know that he is logical and just, (God's mind and will trumps ours) —and our reasoning that he would not hold us responsible for sin we willfully choose, even if our choices were caused, does not hold up.
(I could have added in
@Clare73 's argument —that God is not unjust to hold us responsible for choices freely made according to our inclinations. By that use, after all, no matter the causes, we freely do choose. But that is not an argument of the same type as these, though it would probably have been better understood by you. I could also have repeated my logical arguments, but I've already done that. So I'm coming at this from a different tack.)
2. We don't always choose sin. Sometimes we do, sometimes not. But if the reason I rob the bank is because God has created me a certain way and given me the will to do it, how am I responsible when God is the cause for my will to do it? In the same way, how can I be responsible for other sins?
Are we responsible for being in opposition to God? Well, yes and no! We are not responsible for being born with a sinful nature, but we are responsible for how we live with that sinful nature. How is it possible to be responsible for how I live, if God is the one causing my will to be this way?
You are responsible for robbing the bank; the reason you rob the bank is because you willfully chose to do so, even if there were other sure causes at work to bring you to that point, and to cause you to choose what was already determined for you to do.
You yourself said he caused you to be born with a sinful nature. And you have at other times agreed with at least the Arminian reasoning, that one will live according to that sinful nature until God changes something, no? Arminianism likes "prevenient grace" but it is a necessary change, no?
3. I'm not sure where you are going here. How does that explain how we are responsible without "uncaused" free will?
Because 'uncaused free will' implies not only guilt, as you claim, but it also implies credit for righteous choices —that is, unless you wish to credit mere chance...
4. I don't think the discussion is about guilt, but whether we logically are responsible for what we do.
Ok, Adam's sin. Are we logically responsible for Adam's sin? How could we? We were not even there. Again God could hold us responsible for Adam's sin, but would it be just? It's like I'm responsible for being born an homosexual. Isn't God rather holding us responsible for the things we are logically responsible for? Like living an homosexual lifestyle, or robbing a bank.
Are you saying he imputes the guilt but that he is not logically and justly holding you responsible? That imputation of itself condemns us. And he does have that right to do with his creatures as he pleases; and nobody has, nor does their opinion have, the authority (not to mention the wisdom) to proclaim him unjust. I would say he is more than just to proclaim his whole created race of humans guilty, on the basis of Adam's sin alone, whether we can logically see it or not. What do we know of individuality vs corporate, or even of what sin really is, nevermind the differences in the levels of hierarchy between God and man, and type of economies of God vs man and the relationship between them?
Even if you are right that God imputed Adam's sin on us, it doesn't mean we are logically responsible. It's more the answer: God is God and He can do things in any way He wants. But that's not an argument for us logically being responsible.
It is an argument for the fact of it, or at least, the removal of the argument against it. If God imputed the guilt of Adam's sin on us (and I see no way to say he did not, according to Scripture), yet we cannot see how that is fair, how can we say he would not be fair in holding us responsible for willfully choosing to do that which we are by chain of causation, caused to do? Or, if we do find it fair for him to do so, how is it any less fair for him to hold us responsible for sin we willfully chose and were caused to choose?
