John Bunyan was a leading Puritan preacher during the 17th century. Bunyan was also well known for being a prolific Christian author and The Pilgrim's Progress is regarded as one of the most famous books of Christian literature ever written. The Acceptable Sacrifice is a devotional in which Bunyan provides an exposition of Psalm 51:17 in order to show the Christian reader how a broken heart can be kept strong and why having one is so acceptable to God.
