The last major section of Isaiah deals with the necessity of living out the righteousness of God (cf. Rom. 12-16). These chapters emphasize what the characteristics of the servants of the Lord should be. Again, the focus is on Israel primarily but not exclusively. All God's people are in view, though God's will for Israel and His promises to Israel were Isaiah's chief concerns.633
"These chapters are about the internalization of the law by means of an intimate relationship with the God who alone can enable people to live holy lives."634
This section also clarifies the relationship between works and grace, both of which Isaiah spoke of as essential in his earlier chapters.
The structure of this section is as follows.635
