I know.
I have read it many times in the past.Read John 17:5
"And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was."
Your proof text doesn't say that, but it does say that Jesus had glory before the world existed. And it implies that He was re-given that glory at some point after He made the request you quoted.That's because He has ALWAYS been God.
The verse you quoted make it clear that there was a time when Jesus lacked glory. It spanned at least about 33 years. Otherwise, His request to be given the glory that He had before the world existed wouldn't make any sense.Jesus took on flesh... and was fully man the WHOLE time still being fully God.
There was a time when Jesus lacked glory. It spanned at least about 33 years.There was never a time when Jesus was a "mere mortal."
Anyway, none of this refutes or invalidates my statement that
“Jesus was once mortal, but is now immortal, & glorified...”
My statement remains as true as ever.
