Back to the purpose of my OP - providing arguments against Arminianism, not simply arguing with Winman.
I've seen this credited to the Puritan John Owen. I assume that is indeed the case.
The Father imposed His wrath due unto, and the Son underwent punishment for, either:
All the sins of all men.
All the sins of some men, or
Some of the sins of all men.
In which case it may be said:
That if the last be true, all men have some sins to answer for, and so, none are saved.
That if the second be true, then Christ, in their stead suffered for all the sins of all the elect in the whole world, and this is the truth.
But if the first be the case, why are not all men free from the punishment due unto their sins?
You answer, "Because of unbelief."
I ask, Is this unbelief a sin, or is it not? If it be, then Christ suffered the punishment due unto it, or He did not. If He did, why must that hinder them more than their other sins for which He died? If He did not, He did not die for all their sins!"

Which of these statements is true?
1. Christ died for some of the sins of all men.
2. Christ died for all the sins of some men.
3. Christ died for all the sins of all men.
No one says that the first is true, for then all would be lost because of the sins that Christ did not die for. The only way to be saved from sin is for Christ to cover it with his blood.
The third statement is what the Arminians would say. Christ died for all the sins of all men. But then why are not all saved? They answer, Because some do not believe. But is this unbelief not one of the sins for which Christ died? If they say yes, then why is it not covered by the blood of Jesus and all unbelievers saved? If they say no (unbelief is not a sin that Christ has died for) then they must say that men can be saved without having all their sins atoned for by Jesus, or they must join us in affirming statement number two: Christ died for all the sins of some men. That is, he died for the unbelief of the elect so that God's punitive wrath is appeased toward them and his grace is free to draw them irresistibly out of darkness into his marvelous light.
