My post was a snippet from a small book of sermons from William Gadsby who was a Strict and Particular Baptist (England). The full title of the said sermon is: The Present State of Religion;or, What are the people miscalled Antinomians?;being a dialogue between Love-Truth,Investigation and Others.
It runs for 48 pages.....

Where did I get it ? from a second-hand book shop here in Bournemouth , England.
