Isaiah, author of the Biblical book that bears his name, is often considered the greatest of the prophets writing in the Old Testament. His ministry began in 740 B.C., and he lived until at least 681 B.C. He had a wife and at least two sons, and probably lived in Jerusalem for most of his life.
The Book of Isaiah has been referred to as a mini-Bible. Just as the Bible has 66 books, Isaiah has 66 chapters, and just as the Bible is divided into 39 Old Testament books and 27 New Testament books, the Book of Isaiah has a similar division. The first 39 chapters (most likely written shortly after 701 B.C.) pronounce judgment and condemnation on an immoral and idolatrous people, and the last 27 chapters (probably written later in Isaiah’s life) proclaim comfort and hope in the coming Messiah, who is both King and Savior. Throughout both sections of the book, Isaiah often refers to God as “the Holy One of Israel.” The Book of Isaiah contains many visions of the future that were fulfilled in very specific ways, including many Messianic prophesies. Isaiah 53 is one of the most vivid depictions of Jesus in the Old Testament.
The name Isaiah means “the Lord (i.e. Yahweh) saves.” The Lord in His grace and mercy saves us through the death and resurrection of the Messiah Jesus.
