Can't vs won't I'd say is a distinction without a difference
Let’s look at your logic here. By your standard:
Those who chose not to believe in Christ in truth
could not have believed because “can’t” and “won’t” are distinctions without a difference. Therefore, your logic dictates, salvation was only a legitimate possibility and Christ the Savior for only those who
did believe OR God’s offer (Jesus’ death on the Cross) was but a mockery.
So, you believe that all of those people who
did not believe could not believe (they lacked not just the will but an actual capacity to believe). If the lost are not judged that they have not believed, and if the judgment is not that Christ has come men loved the darkness instead because their deeds were evil as everyone who does evil hates God and does not come for fear their evil acts be expose....if all of that is false and those who reject Christ do so simply because they lack the capacity to do otherwise, then why the condemnation?
You seem to have an understanding that I would call extreme or “hyper” Calvinistic, in one way (you reject choice as being a matter of the will, but instead view "can not" and "will not" as distinctions without a difference, when in fact they are distinctions that make all of the difference.
And you are wrong. There are things I can do, but I choose not to do. And there are things I cannot do, so my desire to do them is irrelevant. And there are things I can do, but am unable to do them because of my will.
Since you believe "will not" and "can not" are the same, then you believe those who in fact would not believe could not believe. Whether will or capability, your conclusion is that those who are not saved could not have been saved. Is it because salvation was not offered to them or was God mocking them?
