"Arminian exegesis"??

Yes, God is not willing that any should perish, but as is the anaology in 2 Peter, and like in the days of Noah, he will not always strive with man (Genesis 6-3). Both truths hold true to bible literature, in spite of some of the preposterous interpretations forwarded in order to try and be rid of a problem verse. Forget Arminius, look at what CALVIN had to say about 2 Peter 3-9. It`s also worth noting that many Calvinists, past and present, agree with Calvin`s most natural and obvious reading of the text. Google around. I could provide links but my post count is too low to do so.
But the Lord is not slack, or, delays not. He checks extreme and unreasonable haste by another reason, that is, that the Lord defers his coming that he might
invite all mankind to repentance. For our minds are always prurient, and a doubt often creeps in, why he does not come sooner. But when we hear that the Lord, in delaying, shows a concern for our salvation, and that he defers the time because he has a care for us, there is no reason why we should any longer complain of tardiness. He is tardy who allows an occasion to pass by through slothfulness: there is nothing like this in God, who in the best manner regulates time to promote our salvation.
And as to the duration of the whole world, we must think exactly the same as of the life of every individual;
for God by prolonging time to each, sustains him that he may repent. In the like manner he does not hasten the end of the world, in order to
give to all time to repent. This is a very necessary admonition, so that we may learn to employ time aright, as we shall otherwise suffer a just punishment for our idleness.
Not willing that any should perish.
So wonderful is his love towards mankind, that he
would have them all to be saved, and is of his own self prepared to bestow salvation on the lost. But the order is to be noticed, that God is ready to
receive all to repentance, so that
none may perish; for in these words the way and manner of obtaining salvation is pointed out. Every one of us, therefore, who is desirous of salvation, must learn to enter in by this way. But it may be asked, If God wishes none to perish, why is it that so many do perish? To this my answer is, that no mention is here made of the hidden purpose of God, according to which the reprobate are doomed to their own ruin, but only of
his will as made known to us in the gospel. For
God there stretches forth his hand without a difference to all, but lays hold only of those, to lead them to himself, whom he has chosen before the foundation of the world.
But as the verb
choresai is often taken passively by the Greeks, no less suitable to this passage is the verb which I have put in the margin, that God would have all, who had been before wandering and scattered, to be gathered or come together to repentance.
