One of the major themes of Isaiah's writings is the restoration of the Jews in the latter days. This may be because he spent so much time prophesying of the imminent destruction of the Northern Kingdom, that he longed for a better day—a day when Israel would again be blessed and protected by the Lord. This blessing won't come to full fruition until the Lord himself sets his foot on the Mount of Olives and begins to fight Israel's battles. Therefore, the writings of Isaiah are full of hopeful, optimistic, and happy representations of what things will be like in that day when the Lord saves Israel, The wolf also shall dwell with the lamb…the earth shall be full of the knowledge of the Lord…the Lord shall be unto thee an everlasting light…Ephraim shall not envy Judah, and Judah shall not vex Ephraim…they shall beat their swords into plowshares…he that remaineth in Jerusalem, shall be called holy…the ransomed of the Lord shall return, and come to Zion with songs and everlasting joy upon their heads…they that wait upon the Lord shall run and not be weary; and they shall walk, and not faint…with everlasting kindness will I have mercy on thee…Break forth into joy, sing together, ye waste places of Jerusalem: for the Lord hath comforted his people, he hath redeemed Jerusalem.
