moses is a prophet or messenger of god just like jesus or mohammad. they are not subject to the same tests. some claim they aren't even human. according to my understanding paul also has been directly chosen by god for a specific mission. i haven't looked at the miracles jesus performed because, since them happening can't be verified and i can't witness them myself they are quite irrelevant for me. i also didn't get the impression that everyone witnessing a miracle was automatically convinced.

also the existence of exceptions doesn't negate that the rest of us have that choice.
