Puritanism in the seventeenth century had many shining lights. Of these, James Durham (1622-1658), ranks alongside the greatest for his theological depth, faithful preaching, and moderate spirit. Durham's exposition on Revelation contains treatises of the purest of theological gold with extended essays on the Trinity, the call to the ministry, the nature of justification, and more: it is Reformed thought at its best and has been valued through history. His contemporary, Robert Blair said "Many Writers have done worthily, but thou excellest them all." C. H. Spurgeon said, "It would not be easy to find a more sensible and instructive work than this."
