Chapters 24–27 of Isaiah have been described as his ‘Tale of Two Cities.’ Like Charles Dickens’ well-known novel, they speak of a terrifying urban convulsion which has widespread reverberations. But the difference between them is of course far greater than any similarity.Dickens recorded the ‘Terror’ of the French Revolution that sent shock waves from Paris to London (and across Europe to the New World) to which he could only append the desirable possibility of a ‘resurrection-like’ renewal. Isaiah’s ‘two cities’ are an anticipation of ‘Babylon’ and the ‘New Jerusalem’ in John’s Apocalypse, and what he says about each is certain and everlasting.The events of which Isaiah speaks take place ‘in [or] on that day.’ This is a recurring expression in chapters 24–27 of his prophecy. They refer to ‘the Day of the Lord’ and introduce acts of the Lord’s judgment and salvation. Following the text, these will be considered in seven sections or ‘movements’ with 24:1-20 providing a kind of ‘overture’ to the whole since it deals with both those realities.Isaiah 24–27 is a magnificent display of ‘the Day of the Lord’ in judgment and salvation, and also of godly rejoicing and waiting for it in dark days. It comports with ‘the already and not yet’ of Christian living, and so Christians should find strength and comfort in these chapters as they look forward and upward to the Lord’s return and ‘the new world’ that God has promised.
