The passage which I quoted proves that even those who are perishing could have believed the gospel if not for the fact that their minds were blinded to its truth by the god of this world.
Do you think Paul was wrong about that?
In answer to your point I will quote John Wesley, and his points are shared by most of the Calvinists:
"The sum of all is this: the almighty, all-wise God sees and knows, from everlasting to everlasting, all that is, that was, and that is to come, through one eternal now. With him nothing is either past or future, but all things equally present. He has, therefore, if we speak according to the truth of things, no foreknowledge, no afterknowledge. This would be ill consistent with the Apostle's words, 'With him is no variableness or shadow of turning;' and with the account he gives of himself by the Prophet, 'I the Lord change not'...Not that God has any need of counsel, of purpose, or of planning his work beforehand. Far be it from us to impute these to the Most High; to measure him by ourselves! It is merely in compassion to us that he speaks thus of himself, as foreknowing the things in heaven or earth, and as predestinating or fore-ordaining them. But can we possibly imagine that these expressions are to be taken literally?" [emphasis mine] (John Wesley, Sermons on Several Occasions, 1771, Second Series, "On Predestination," Sermon #58; Christian Classics Ethereal Library).
What a perfect time for a little debate on TOL concerning the beginning of the present dispensation and the beginning of the Body of Christ.
But I doubt Arnold will be up to the challenge because he lacks the kind of confidence needed for such a debate.
