Isaiah is called "The Messianic Prophet" because of his many descriptive prophecies concerning Christ, our Redeemer, including his virgin birth, his death for our sins, his burial, and his resurrection. Isaiah revealed the gospel of Christ in advance. (1 Corinthians 15:1-4) The Book of Isaiah is the first of the Major Prophets. It is like a miniature Bible with its sixty-six chapters. The first thirty-nine chapters are like the thirty-nine books of the Old Testament with judgments upon sinful men. But the last twenty-seven chapters have a message of hope corresponding to the twenty-seven books of the New Testament. Isaiah's people would be punished for their sins, but repentance would bring forgiveness. The prophet predicted not only the destruction of Jerusalem and the temple but also their restoration. Isaiah had a message of hope for his nation and for the world. The theme of the book is in Isaiah 1:18, "Though your sins are as scarlet, they shall be white as snow."
