This work by master theologian Edmund Calamy is a work of the highest order on covenant theology. Calamy says that there are two covenants, following the received standards of the Westminster Confession. There is the Covenant of Works, where all men by nature lie under the pollution and guilt of Adam’s sin, and liable to all the curses and penalties due to them for breach of that covenant. And then, secondly, there is the Covenant of Grace which God the Father made with Jesus Christ from all eternity to save some of the posterity of Adam. Calamy carefully and methodically explains that the Covenant of Grace was prepared and readied against the fall of Adam to take place at the very moment of his fall; otherwise the justice of God would have immediately seized on all of creation under heaven, and consumed them to nothing. But Jesus Christ came with the covenant in his hand saying, “Be gracious unto him, and deliver him from going down to the pit, I have found a ransom,” (Job 33:24). Calamy proves that the Covenant of Grace was made with Jesus Christ, and this was the contract of God the Father with God the Son from all eternity as mediator for the salvation of the elect.
