Human nature in its fourfold state ... In several practical discourses

4. Great is the difficulty in Adam's sons their parting with the law, as a covenant of works. None part with it in that respect, but these whom the power of the Spirit of grace separates from it. The law is our first husband, and gets every one's virgin-love.
