From the Editors Preface: Owen explores in great depth what it means to kill sin in our lives. Killing sin is a path that we take toward personal holiness. It is how we maintain communion with God by honoring him with our obedience, exercised in cooperation with, and under the power of, the Holy Spirit. Holiness is not a list of dos and donts, like not swearing or not drinking alcohol. That would only be returning to the law that Christ freed us from.
