Based on the theme of spiritual regeneration, The Hammer of God reads like a good detective story, immersing the reader in the unfolding events that present a spiritual drama of life and death, of despair and hope, of upheaval and peace, of sin and grace. Faith comes down to a matter of relying either on our own accomplishments to be right with God or on receiving as a free gift by grace the righteousness Christ gained for us. This basic question of faith remains the same today as in generations past.

The revised edition includes a final chapter never before published in English, as well as a new preface, extended biography of author Bo Giertz, and new introductory notes.
