Isaiah 57:14
14He will say, “Build up, build up, prepare the way! Remove the stumbling-block out of the way of my people.”
Wesley: God will raise up a man who shall say with authority and efficacy. Cast up—make causeways for safe passage, and remove all that may hinder their return.
The road home is commanded, not merely wished. Obstacles can be taken up. My people’s way is restoration language—return from exile, and, in the gospel’s width, a path cleared for whoever will walk it under grace.
Calvin: lest the land-promise of v. 13 look ridiculous once they are driven out, a second promise is added—they shall be brought back. He meets the doubt of a long banishment. The words agree with Isaiah 40:1–4. He addresses Cyrus and Darius, whose minds the Lord inspired to open the path.
If the Lord determines to bring back his people, there must be a road. Every bar is removed because he has promised the return and is their leader in the journey.
