CLAIM: Isaiah describes the healing of the land and the people of Israel in the Millennial Kingdom. While this was partially fulfilled in the return of the exiles from Babylon, the permanence of everlasting joy, and the complete elimination of sorrow envisaged in verse 10 indicates a greater fulfillment. The physiological restoration of verses 5-6 began to be fulfilled in the ministry of Jesus and the apostolic church. Israel will see a full ecological restoration (vv. 1, 2, 7) and deliverance (v. 4) during the time of Jesus’ Second Coming.
Mixed.
If it was not directly fulfilled in Jesus’ day, it certainly is today.
Let the weak say I am strong in Him. Let the poor say I am rich in Him. The blind will see and the deaf hear. The highway of holiness will be built up. This is certainly true in our day, although it is ongoing throughout the church. It may increase as certain events approach, seeming to have a greater fulfillment, but this is the promise of His Kingdom, from the Beatitudes through all of Jesus’ teaching.
If the restoration of the nature is truly literal in this passage, it would fit under the Romans 8 description of even the creation being liberated.
