Mat 1:23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
"God with us" when referring to the birth of Jesus Christ certainly sounds like Matthew thought Jesus was "God with us".
Why is this such a gem? Yeshua, who will rule and sit on David's throne in God's kingdom, in the "athid lavo" (millenium if you will), this entire concept cannot be considered "God with us"? Not when considering the context:
Mat 1:21 "She will bear a Son; and you shall call His name Jesus, for He will save His people from their sins."
Mat 1:22 Now all this took place to fulfill what was spoken by the Lord through the prophet:
Mat 1:23 "BEHOLD, THE VIRGIN SHALL BE WITH CHILD AND SHALL BEAR A SON, AND THEY SHALL CALL HIS NAME IMMANUEL," which translated means, "GOD WITH US."
The bible is referring to Jesus Christ, when in the flesh as "God with Us" not "God will be with us in the future millenial kingdom".
Still makes perfect sense within that context. Unless you're retroactively trying to read a pagan Man/god theology into Hebrew scriptures.
