Notice that Isaiah's proclamation of Messianic praise extends from the birth of the Savior clear down to that magnificent moment of triumph at the beginning of the Millennium when he becomes Lord of Lords and King of Kings. At that moment he will be called "Wonderful," which means "of the greatest excellent." He will also be called "Counselor" which is most appropriate since he served as a counselor at the right hand of the Eternal Father ever since our pre-mortal estate.
He will also be called "The Mighty God," which is a status he achieve in the pre-earth life as a member of the First Presidency of heaven. The word "God" means the ultimate in goodness. Beginning with verse 7 Isaiah contemplates the Savior's Millennial reign. After the earth has been perfected and has been completely cleansed of all wickedness, Jesus will extend his government world-wide. It will be government of peace that will extend from pole to pole and minister justice and fair judgment wherever problems arise. This will not come about by accident or happenstance but it will be by design and the zeal of the Lord pressing forward until all these things are accomplished.
