In a great example of evangelical theological retrieval, McCulloch seeks to shed light on the biblical counseling movement. He succeeds through a combination of historical theology (retrieving the theology of 17th century giant John Owen), theology refresh (doctrine of God, Christology, anthropology, hamartiology, soteriology-sanctification), and practical theology (how we grow in grace and help others do so). This is recommended for those interested in biblical counseling, the biblical counseling movement, a biblical understanding of how sanctification works, John Owen, and those interested in how the work of the Spirit in the past can shed light on his work in the present.
