The Comfortable Chambers, Opened and Visited is a 1728 sermon and devotional tract by Cotton Mather (1663-1728), the Boston Congregationalist minister who was the most prolific and best-known figure of late Puritan New England. Mather published more than four hundred works across his career and was central to the religious, scientific, and political life of Massachusetts. This piece, issued in the year of his death, is a meditation on Isaiah 26:20 and offers consolation to readers facing illness, bereavement, or the imminence of death. The sermon stands in the long Puritan tradition of consolatory writing and shows Mather’s late style at its most pastoral. The book is a primary source for the religious culture of early eighteenth-century New England. Free PDF download available on BDeBooks.
