Both were asking “how can such a thing happen?” The difference was in how did they say it, what did they mean. We know that Mary submitted herself to God’s will, but we don’t know about Zachariah. Was he telling the angel it could not happen? Was he demanding proof? I don’t know. All I’m saying is that whatever was in Zachariah’s heart can probably explain Gabriel’s reaction!
“All Im saying is that whatever was in Zachariahs heart can probably explain Gabriels reaction!”
Exactly!
