The Gospel Mystery of Sanctification by Walter Marshall

The Gospel Mystery of Sanctification by Walter Marshall is considered the most important book on sanctification ever written. The author grew up, he cut his teeth, so to speak, under the influence of Richard Baxter who lived between 1615 and 1691. So we're looking at this from a historical vantage point? This is the 21st century! We don't wear the kind of hats that they were in 1600s. But it's still important now because many people have a crush on Richard Baxter.
