Originally published in 1692, The Gospel-Mystery of Sanctification is a classic work of Reformed theology. Marshall's central argument is that true sanctification is the result of faith in Christ and the sanctifying work of the Holy Spirit, rather than a mere matter of self-discipline or moral effort.
