John Bunyan's The Water of Life (1688) shows the richness and glory of the grace of the Gospel as set forth in the Scripture. Bunyan uses the water of life as a metaphor for the spirit and grace of God that shows the way to complete redemption from sins of life. The book further explores the greatness, the spring, and the nature and quality of this water of life that cures all the spiritual and physical maladies of man.
