B. God's atonement for Israel chs. 49-55

In the previous section (chs. 40-48), Isaiah revealed that God would redeem His servant Israel from Babylonian captivity by using one of His servants, Cyrus. Israel's sin had resulted in her going into the furnace of Babylon for a period of refinement.

In this section, the prophet revealed that God would also deal with the more serious problem of sin in Israel that had resulted in her captivity. He would do this by using another Servant of His, the Messiah. This Servant would not only take care of Israel's sin problem but that of the whole world. Thus Isaiah passed from dealing mainly with physical deliverance to dealing with spiritual salvation, from Cyrus to Christ.

 1. Anticipation of salvation 49:1-52:12

This first segment focuses on the anticipation of salvation. Israel needed to believe the promises of God concerning the coming salvation. The possibility of a restored relationship between Israel and her God becomes increasingly clear as this section unfolds. Likewise, the cosmic dimension of this salvation becomes increasingly obvious. The section reaches its climax with the announcement that God has won victory and the people are free (52:7-12).

 2. Announcement of salvation 52:13-53:12

The second segment of the section in Isaiah dealing with God's atonement of Israel (chs. 49-55), after the anticipation of salvation (49:1-52:12), is the announcement of salvation. This is the fourth, final, and most famous Servant Song.

"The profoundest thoughts in the Old Testament revelation are to be found in this section. It is a vindication of the Servant, so clear and so true, and wrought out with such a pathos and potency, that it holds first place in Messianic prophecy."⁵⁶²

The reader of the promises that God would redeem His people with His mighty arm (cf. 50:2; 51:5, 9; 52:10) could reasonably expect that redemption to come with a great display of overwhelming power. But the careful reader of the previous Servant Songs has picked up some hints that the Servant would not fit the mold of the traditional action hero. In this passage Isaiah filled out the previously sketchy picture of the Servant with more detail concerning His work, character, and nature. God's greatest power is evident in His ability to return love and forgiveness for hatred and injustice, not in His ability to crush all opposition.

"No subject connected with the Old Testament has been more discussed than the question of the identity of the Suffering Servant in Deutero-Isaiah."⁵⁶³

This Song consists of five stanzas of three verses each. The first and last stanzas record God's commendation of the Servant, and the middle three describe the Servant's commitment to God's will. The central one focuses on His substitute death. Two key contrasts mark the passage: the contrast between the Servant's humiliation and His exaltation, and the contrast between the reader's expectations of the Servant and reality.⁵⁶⁴

 3. Invitation to salvation chs. 54-55

This section of Isaiah's prophecy joyfully announces Yahweh's salvation and invites participation in it. Joy and invitation are the result of the announcement of salvation through the Servant (52:13-53:12).

"The first two Servant Songs are followed by tailpieces concerned with divine confirmation of the Servant's task and promises of its success (42:5-9; 49:7-13). The third and fourth Songs are followed by invitations to respond to the Servant and what he has done (50:10-11[; chs. 54-55]). Response is the keynote of chapters 54-55. . . . In his saving work, the Servant has done everything, removing sin, establishing in righteousness, creating a family. The way is therefore open for response, pure and simple: to sing over what someone else has accomplished (54:1), to enjoy a feast for which someone else had paid (55:1)."⁶⁰²
