‘Grace Abounding to the Chief of Sinners’ by John Bunyan is one of the classic spiritual autobiographies. It was composed while Bunyan was serving a twelve-year prison sentence in Bedford gaol for preaching without a license and was first published in 1666. This book is Bunyan’s pilgrimage from a profane life filled with cursing and blasphemy, to becoming one of the most prominent religious authors in English literature. Throughout his account, Bunyan relies closely on the firm promises of God's Word as a spiritual defence. Bunyan explains his previous struggles with sin, temptation, and a conflicted conscience. This testimony serves to truly magnify how the grace of God alone saved the doomed life of this hurting sinner. His works have gone on to become some of the most influential pieces of Christian literature of all time. This honest account offers real hope and proof of a gracious God who loves His people unconditionally and with life-changing power. It captures amazing moments of self-discovery, and narrates the agonizing turmoil of doubt.
