Jonathan Edwards's The Distinguishing Marks of a Work of the Spirit of God is one of the great classics of revival literature. In it Edwards examines the true and false signs of a revival based on the exhortations found in 1 John 4. Now a complete version of his work is made more accessible through the modernization of the text and addition of explanatory footnotes from editor Archie Parrish. A historical introduction by R.C. Sproul, as well as William Cooper's original Preface, is also included. This work provides more than just insight into the Great Awakening of Edwards's day. It is a guide for all revivals in all times.
