I see both "unbelievable things in the story" and "that God does unbelievable [supernatural] things in the scriptures". Chief among them--loving people like us who have opposed Him.
And for many years now, I've always taken Paul's nonchalance as indicative of his assurance that he'd be just fine--there's a parallel story where someone dies during his sermon and Paul calmly goes over and resurrects the chap.
I think you are being, well, you, I mean, I believe in a virgin birth and Christ's resurrection from the dead--and also I believe/know/understand that I now bear eternal life and will resurrect from the dead as well.
What is your point? What are you driving at? That people who love Jesus and have been saved believe supernatural occurrences are simple for a powerful being to perform? You are wasting both of our time IMHO.
Point? At its most basic, it is cultural anthropology,
a study of the habits of Christians, probing to see
where limits are. For some, the bible is literal, every word.
Others will accept that the flood is nonsense.
The grotesque extremes to which some will go to try
to deny things like the failure of the Tyre prophecy to
be fulfilled is for sure, a study.
I believe/know/understand ....unbelievable things.
The difference between you and me in this is that
you are capable of just deciding to believe something,
and that as it is
self-deception, I wont do it. Maybe
cannot, I dont, in the event, want to try.
I need to
actually believe something.
I am not entirely sure it works for you either, though
functionally it is the same, as, by dint of long practice,
the decision / belief will settle in and be indistinguishable.
If there is a god, he could of course magic the snake
and make gold of cowpoop, if he so chose.
Given this distinction, that you decide to believe the
unbelievable, and atheists do not, you are wasting your
time, and ours, by having any discussion of these
matters. Why do you do it?
