Isaiah is known as the 'evangelical prophet' of the Old Testament for his detailed Messianic prophecies. Written during a period of national crisis in Judah, the book combines severe judgments against injustice with beautiful promises of hope and restoration. Isaiah prophesies the coming of the Messiah, the Suffering Servant, and God's future kingdom. The book divides into two main sections: chapters 1-39 (judgment and hope) and 40-66 (consolation and restoration), offering a panoramic view of God's redemptive plan.
