Few British pastors can claim to have written a book that is amongst the 'life-books of their generation', yet Boston is one. His Fourfold State of Man has been the instrument of countless conversions and could be said to have changed the zeitgeist of his era as effectively as Luther's Commentary on Galations, Alleine's Alarm to the Unconverted, Bunyan's Pilgrim's Progress, Edwards' Sinners in the Hands of an Angry God, Wilberforce's True Christianity or Lewis' Mere Christianity.
"The author, a godly Scottish biographer of Owen and Baxter, here portrays the gentle country pastor whose exemplary devotionto his calling and Hebrew scholarship and linguistic ability added strength to his advocacy of the theology of the Reformers, Puritans and Covenanters, when this was being undermined by the Moderates of his day. It is so good to find a biographer whose affection for his subject does not mar his judgement, but warms the reader's heart. Thomson's fine biography confirms John ‘Rabbi' Duncan's description of Boston as a ‘commonplace genius.' With the emphasis on genius." - Peace and Truth
