I am loving the fact that Sinclair Ferguson is “retired”. He has been more active in writing, and those books have been excellent so far. Devoted to God: Blueprints for Sanctification is no exception. He previously submitted a chapter on the subject to Christian Spirituality in which a number of authors of different persuasions interacted on the subject of sanctification.
Like The Whole Christ, Devoted to God seems to be the fruit of a lifetime of fruitful ministry. You sense that he has thought long and hard about the Scriptures with regard to this subject. It is not superficial or breezy in its approach. In each chapter, Ferguson focuses on one text of Scripture. Those passages are: 1 Peter 1; Romans 12:1-2; Galatians 2:20; Romans 6:1-14; Galatians 5:16-17; Colossians 3:1-17; Romans 8:13; Matthew 5:17-20; Hebrews 12:1-14; and Romans 8:29. The principles are derived from the texts that Sinclair uses. This is not a “proof-texting” approach, but a very exegetical approach.
His approach focuses on sanctification as devotion. God is devoted to making us devoted to Him and His glory through our union with Christ by the Holy Spirit. This is realistic in its approach, as he notes “Instead of being wholly yielded to Christ we discover instead that a stubborn and sinful resistance movement retains a foothold in our lives.” (pp. 5)
Beginning with 1 Peter, he focuses on our identity in Christ in the face of affliction. We have graciously received a new identity which requires a new life. He notes the distinctions between justification and sanctification, but also notes that both are necessary for salvation tying these in to our union with Christ and the reality of regeneration. In our union we receive what Calvin calls the “double grace” of justification and sanctification. Regeneration which is necessary for justification (we won’t believe until God regenerates us) is also the beginning of our sanctification.
Another focus he begins in the first chapter is the trinitarian nature of our sanctification. The Father foreknew us and chose us, the Spirit sets us apart and we are purified by the Son. Your sanctification, if you are a Christian, is the desire and purpose of the Father, Son and Spirit. In 1 Peter we see that they use, among other things, trials to accomplish this great purpose.
In other chapters he reminds us that the commands (imperatives) flow from the gospel (indicatives). It is all of grace, being produced by the gospel. He reminds us, particularly in Romans 12 that our sanctification “takes place in and through the body.” We are not gnostics. We are a body/soul unity and sanctification includes both the inward devotion and the physical devotion. Sin and sins affect our bodies (weakness, addictions which are spiritual and bio-chemical, disease etc.) and so sanctification does as well. Just as sin affects our minds, so does sanctification.
Ferguson covers plenty of ground in this volume, and he covers it well. Some of these are difficult texts with difficult concepts, especially Romans 6, and he is very helpful in understanding them better as well as applying them to the subject at hand. As I preach through 1 Peter I find himself looking back to the material here on that letter. I anticipate returning to this book whenever I preach on any of these texts. I anticipate pointing others to this book and walking with others through this book for years to come.
Sinclair Ferguson has again written on the best and most helpful books I’ve read. His retirement has been very, very good to me. If you read his books, you will discover it was very good for you too.
