'Man' in the Bible

From: Paul an apostle not sent from men or by a man, but by Jesus the Messiah, and God the Father, who raised him from the dead

For I did not receive it from a man, nor was I taught it, but it was revealed to me by Jesus the Messiah.

The only thing they kept hearing was this: "The man who used to persecute us is now proclaiming the faith he once tried to destroy!"
