'Grace Abounding to the Chief of Sinners, written during [Bunyan's eleven year] imprisonment, is the spiritual autobiography of Bunyan, the traveling tinker who became the eminent preacher and author. It is in the genre of Augustine's Confessions and Thomas a Kempis's Imitation of Christ....Written in 1666, Grace Abounding chronicles Bunyan's spiritual journey from a profane life filled with cursing, blasphemy, and Sabbath desecration to a new creation in Jesus Christ.' -from the original publisher's Forward
