20 No longer will there be there a child whose days are cut short, or an old man whose days have not come to their full measure: for the young man at his death will be a hundred years old, and he whose life is shorter than a hundred years will seem as one cursed.
Matthew Henry's Commentary on Isaiah 65:20
Commentary on Isaiah 65:17-25
(Read Isaiah 65:17-25)
In the grace and comfort believers have in and from Christ, we are to look for this new heaven and new earth. The former confusions, sins and miseries of the human race, shall be no more remembered or renewed. The approaching happy state of the church is described under a variety of images. He shall be thought to die in his youth, and for his sins, who only lives to the age of a hundred years. The event alone can determine what is meant; but it is plain that Christianity, if universal, would so do away violence and evil, as greatly to lengthen life. In those happy days, all God's people shall enjoy the fruit of their labours. Nor will children then be the trouble of their parents, or suffer trouble themselves. The evil dispositions of sinners shall be completely moritified; all shall live in harmony. Thus the church on earth shall be full of happiness, like heaven. This prophecy assures the servants of Christ, that the time approaches, wherein they shall be blessed with the undisturbed enjoyment of all that is needful for their happiness. As workers together with God, let us attend his ordinances, and obey his commands.
