Average humans have many limitations.
Some may know how to swim well, but the same person may not know how to play the piano well.
Etc.
What if I told you an average prophet has a really high IQ ? I believe Jesus had an IQ of 777.
They are the ones who can learn to speak 100 different languages, who can also learn to skateboard on handrails, who can also learn to make the finest pizza in Italy: one person doing many things perfectly/professionally.
And since they are prophets, they can also prophesy.
Unlike average humans, an average prophet does not have too many limitations. If any.
