THE GREAT MYSTERY OF THE COVENANT OF GRACE

Samuel Petto’s ‘Great Mystery’ is a classic Puritan treatise on the covenant of grace, showing how God’s eternal pact with the elect is the golden thread that binds Scripture together. Petto explains the covenant’s origin, administration, and consummation, then applies the doctrine to assurance, obedience, and comfort. The style is theological yet tender, making the book suitable for both academic study and private devotion. A reliable guide for anyone who wants to understand how the old and new covenants form one unfolding story of redemption.
