Composed and published while John Bunyan (1628-1688) was in prison for his religious principles, Grace Abounding is an extraordinary spiritual autobiography. It was written in an age when religious radicalism was regarded as socially subversive, and is a haunting, often harrowing and ultimately inspiring account of his inner life: his long struggle with and eventual triumph over doubt and despair, his spiritual regeneration and his subsequent emergence as a preacher and writer of great imaginative power. God and Satan are the chief protagonists in Bunyan's drama, existing not as theological concepts but as terrifyingly immediate adversaries in the competition for his soul. Yet he finds his spiritual defences in the Bible, and Grace Abounding charts his passionate and imaginative involvement with this ultimate source of wisdom.
