CLAIM: Isaiah describes Israel’s rebellion and injustices (vv. 14-15) during history as well as at the end of the age when God’s judgments are fully released (v. 18). At that time, Jesus will war against His enemies when He returns to deliver Zion (vv.17-20) from her sin and her oppressors (Antichrist). God as a Man is the great intercessor who will establish justice among the nations.
The judgment (v18) need not refer to end-times judgment. The chapter ends, however, with the promise of the Spirit being given, in other worse, Pentecost with the 120 in the upper room. The Lord looking to achieve righteousness (v16) after finding none is to be seen only and specifically to the first coming. Jesus achieved this on the cross, and the Father achieved it through raising Him from the dead (Ephesians 1:19-20).
Applying this to the future, simply because it speaks of judgment, seems unbalanced, as those in Jerusalem in 70AD were certainly judged. Enough other passages speak of the final judgment to come, and equating every mention of judgment does not strengthen the passage, nor seem to be intent of God’s oracle.
The local was in view, and the Redeemer did come to Zion, to all in Jacob who repented of their sins (Luke 7:30, in rejecting John’s baptism, they rejected the call to repentance, hence this verse is literally fulfilled–Christ came to save sinners, not the self-righteous who thought they weren’t sinners).
