"The arrangement of chapters 40--66 is not accidental. "The Book of Consolation" is divided into three sections; each focuses on a different Person of the Godhead and a different attribute of God. Chapters 40--48 exalt the greatness of God the Father; chapters 49--57, the grace of God the Son, God's Suffering Servant; and chapters 58--66, the glory of the future kingdom when the Spirit is poured out on God's people."
