Only monergistic grace, in which the Holy Spirit sovereignly unites us to Christ, fully preserves the sovereignty, glory and majesty of God in salvation. Matthew Barrett examines and defends monergism's heritage of biblical support, working through effectual calling and regeneration in detail and setting them against the synergistic alternatives.

The book moves from the contemporary debate to monergism in the Calvinist tradition, then through total depravity, the nature of the call, and the new birth, engaging Arminian and other synergistic accounts directly. Barrett writes as a careful systematician, and the documentation is heavy. For readers who want the doctrine of effectual calling argued at length rather than assumed.
