This treatise, written in 1656, is effectively an expanded commentary on the 8th chapter of Romans (particularly verse 3) and the exhortation to mortify (or put to death) the deeds of the flesh. The subtitle of this writings is "...the Necessity, Nature and Means of it: With a Resolution of Sundry Cases of Conscience Thereunto Belonging". The analysis is extensive, touching upon practical ethical and psychological concerns while continually grounded in passages of Scripture. The final chapter treats of the work itself – of putting sin to death, claiming that all previous discussion is preparatory for the essential work – which is of the heart, by faith in Christ.
