The OT predicted that the Savior would be born in Bethleham, be a prophet on the scale of Moses, be a healerand miracle worker, be rejected of His people and killed. It predicted His death would pay for the sins of mankind and that He would rise from tge dead. It predicted that the news of this Savior and His forgiveness of sins would spread around the world with many finding forgiveness through Him. It happened. Emmanual showed.
Until he showed, he could not be claimed as with us. So old "god is with us", never being "with" us, only proves that there was no god with us. Not once was the Jewish Rabbi Jesus, claimed to be Emmanuel.
The Messiah Emmanuel must be a direct descendant of David. Jesus didn't meet this requirement, beings Joesph was not his natural father. The prophecy was not fulfilled.
Nope, there was no Emmanuel, at all.
