This prophecy inspired by God himself through the prophet Isaiah is describing for us a picture of the coming Messiah Jesus Christ.
6 For to us a child is born,
to us a son is given;
and the government shall be upon  his shoulder,
and his name shall be called 
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace.
7 Of the increase of his government and of peace
there will be no end,
on the throne of David and over his kingdom,
to establish it and to uphold it
with justice and with righteousness
from this time forth and forevermore.
The zeal of the Lord of hosts will do this. (ESV)
