It's the old "miracles are false because they are miracles" argument.
Ok, fair enough... I prefer the:
"Miracles are false because there are non-miraculous explanations that fit
as well or better, and also seem to be in harmony with the way the universe
seems to work"
argument.
I cannot say, yet, that the non-miraculous explanations of Isaiah explain the facts
to that level of satisfaction, but I also admit that I am very new to this subject other
than years of highly questionable WT logic.
Therefore, I tend to mistrust my feelings on the matter.
I still wait eagerly to hear WHY the "2nd Isaiah" would write what he did, and why
everyone seemed to accept it as truth at the time and for many years after.
