The nature, certainty and evidence of true Christianity. [electronic resource] : In a letter from a gentlewoman in New-England, to another her dear friend, in great darkness, doubt and concern of a religious nature. I Cor. 1. 26--31. N.B. Tho' this letter was wrote in great privacy from one friend to another; yet on representing that by allowing it to be printed, it wou'd probably reach to many others in the like afflicted case, and by the grace of God be very helpful to them; the writer was at length prevailed on to suffer it--provided her name and place of abode remain concealed.
