Part 1 is the brief biography at the beginning of the book, which supplies some details of Colquhoun’s life including the influence of fellow Scotsman Thomas Boston’s works as well as the Marrow Theology on Colquhoun’s views. Also describes the hunger to hear the Gospel in Scotland, in a time when “moderatism” was dominant. Some youths were walking 100 miles each weekend to hear the Gospel preaching of John Colquhoun. Part 2 will cover the introduction and Part 3 will cover the difference between legal and evangelical repentance
