No Book of the Old Testament is a thoroughly and explicitly messianic as Isaiah. The church father Augustine of Hippo even called it the fifth gospel. It is a book that absolutely drips Christ.
The Servant Songs of Isaiah
And in this Christo-centric book four passages stand out, Isaiah 42:1-9, 49:1-13, 50:4-11 and the most remarkable passage in the Old Testament 52:13-53:12, known collectively as the Servant Songs of Isaiah. These passage not only look forward to the Messiah, but describe the messiah and His earthly ministry in vivid detail.
As one component, along with an upcoming verse by verse exposition of the Songs of Ascent, of a two part preface to a verse by verse exposition of the Gospel of John we are going to look at every verse of these remarkable passages to prepare us for the presentation of the Messiah in John's Gospel.
