This year at GA I went to the RTS Alumni and Friends luncheon. They gave those who attended a gift box that included some books by professors at the various campuses. One book was by J.V. Fesko, Growing in Holiness: Understanding Sanctification, which is part of the Christian’s Pocket Guide series by Christian Focus.
This is the first installment of the series I’ve read, and I’m encouraged to read more. This is a succinct volume on the subject of sanctification that should appeal to those in our congregations who aren’t big readers. It is a mere 3 chapters and 64 small pages. I read it in 3 sittings of less than an hour each.
Fesko does a good job in laying out the material. The 3 chapters are Sanctification Defined, Sanctification Applied and Sanctification Undermined. At the beginning of each chapter he charts the course for the chapter. He interacts with Scripture and the Westminster Confession of Faith.
The one thing lacking is the use of illustrations from everyday life. This results in a more abstract book than some may be comfortable reading.
But what he does is provide a theologically rich summary of the Reformed understanding of sanctification.
Fesko begins with, and often returns to, union with Christ. This is the distinctive view of Reformed Theology. This is rooted in Paul’s theology, not just Calvin. He does explain the “double grace” of justification and sanctification that we receive in union with Christ. We actually receive all spiritual blessings in union with Christ, but these two in particular complement each other and were the focus on the dispute of the Reformation.
Fesko defines each and distinguishes them from one another. But we can’t one without the other. Logically, justification comes first and is the foundation for our sanctification (wherein He make those He has declared positionally righteous personally righteous as well).
Union with Christ is the ultimate basis of sanctification as Christ works in us by the Spirit to make us like He is. This means that like justification, sanctification is by grace alone through faith alone. In Christ we have a new identity that we begin to live out.
In living out that new identity, Fesko discusses the two parts of sanctification: mortification and vivification. Big terms he defines. We put to death that which is associated with Adam our old covenant head because it is corrupt. Sanctification is more than putting sin to death, it is also giving life to virtues or godly character. Both putting the old man to death and bringing then new man to life done in the power of the Spirit. It is a work of God’s free grace, not man’s ceaseless effort.
In Sanctification Applied he goes more fully into the “nuts and bolts” of how this happens. He lays out the means of grace, and therefore the centrality of the body of Christ. Prominence is given to God’s Word: read, preached and in the sacraments. In other words, the church offers us the Word spoken and sacramental. He discusses how we are to pray for God to work so we will understand, believe and obey the Word as revealed in the worship of the church.
In temptation we flee to Jesus in prayer, recalling the Word in its promises and warnings pertaining to our particular need. We are active, not passive, in sanctification. But it is always God who works first: for us and then in us.
In Sanctification Undermined, Fesko identifies the predominant false views of sanctification. He does this briefly, indicating how each of them leads us in the wrong direction. He begins with self-renewal which is rooted in Pelagianism but popularized by Charles Finney as one of his many errors. Sins are habits and we can just stop through the power of our will. It is rooted in self, not grace through faith and our union with Christ. Sanctification without Christ is no sanctification at all.
He then highlights imitation of Christ, particularly the mystical form of Thomas a Kempis. This looks in, not out to Christ. Meditation seems to be separated from the Word of God. (I’m not sure he’s entirely fair to a Kempis, but it has been a number of years since I’ve read him.)
He then outlines Roman Catholicism which has a very different understanding of grace and how that grace is received in the sacraments. Grace is mystical and magical, received through the simple receiving of the sacraments rather than the Reformed understanding of received by faith in the promises of the sacraments.
He then moves to legalism which rightly sees a place for the law, but wrongly depends on the law. This is his opportunity to begin introducing the proper place of the law. But he also shows the weakness of the law. While it reveals, it contains no power in itself. It reveals my sinfulness but cannot change it. I need to be united to Christ!
It’s evil twin is antinomianism which in its various forms indicates that the law has no significant place in our lives after conversion. It is a neglect of the law’s role in revealing righteousness to God’s children. It provides guard rails for us as we grow in Christ. How we lives does matter. The Holy One is making us holy ones.
He includes some book recommendations for further reading. He’s includes some important ones including Murray’s Redemption Accomplished and Applied, Walter Marshall The Gospel Mystery of Sanctification and Edward Fisher’s The Marrow of Modern Divinity. I also recommend these great books for better understanding how the gospel is at work in our sanctification.
Fesko provides us with a clear, succinct volume to help us understand sanctification. This could be a useful book to share with new(er) Christians and to aid conversation about this great work of God in us.
