The final 27 chapters of Isaiah (40–66) resemble the New Testament as they declare hope and grace. It is in these chapters that we are introduced in the clearest way to the Messiah, where judgment and mercy join together in God’s only begotten Son, Jesus. The first 39 chapters reveal man’s need for salvation, and the following 27 chapters show God’s provision for man’s need in the Messiah.
In this last section, God offers through Isaiah promises of hope, comfort, and restoration. In chapters 40-48, the basis of these promises is not man’s compliance but rather it is centered upon God’s sovereignty and majesty. There are 216 verses in those nine chapters, and 115 of them speak specifically of God’s greatness and power. What can we deduce from this truth? Namely, that God’s promises are only appropriated by recognizing His nature and not by us exalting our nature!
