"Bunyan... set about the composition of a book, which, under the title of "Grace Abounding to the Chief of Sinners," gives, as he only could give it, the story of his life. This proved to be one of his most memorable compositions, and associates itself in one's mind with Augustine's confessions and the heart-utterances of Luther. ...This book, which in parts is weird and terrible as his own picture of the valley of the shadow of death, is yet in its alternations a faithful transcript of the writer's soul, and must be read in order to a right understanding of the man as he was, both in strength and weakness."
