The good folks at Cross Focused Reviews have blessed me with another book to review. I was really excited about the prospect of reviewing this book, as it deals with what I see as one of the most neglected aspects of the Christian life as represented in mainstream American evangelicalism: Discipleship. As the title implies, the book also covers the glorious doctrine of Union with Christ—which in its own right is a teaching that is largely overlooked. Jeremy Walker‘s “Life in Christ: Becoming and Being a Disciple of the Lord Jesus Christ” is a welcome addition to contemporary discipleship resources that is not only pastoral, but thoroughly biblical and theologically precise.
In the first chapter, “Looking to Jesus,” he instructs the reader as to how one comes to Christ for salvation. Walker examines the command and invitation of the gospel, as well as the purpose and promise of the gospel. Beginning with the contrast between human depravity and the necessity of regeneration, the author weaves biblical references in and through to help the reader understand the Bible’s teaching of conversion–repentance and faith–and the grace of being declared righteous according to the person and work of Jesus Christ.
In chapter two, Walker seeks to unpack the doctrine of Union with Christ. He points to the teachings of the apostle Paul to explain the Christian’s position “in Christ” and the Christian’s nature as a “new creation.” (pp. 22–27) The author continues by rightfully expounding upon 2 Corinthians 5:17. He explains that for the Christian, “the old has gone and is gone for good; the new has come and keeps on coming.” (p. 28) Walker then closes out the chapter with an evangelistic appeal: “Whoever comes to Christ in faith–repenting of his sins, seeing his misery without Christ, seeking grace to be in Christ–and earnestly desiring that one day he might see and be with Christ–will find Christ to be his Savior and Lord and will enter into the blessed realities of the new creation in himself now and look forward to a life in a new heaven and new earth with Christ in days to come, the very heaven of heaven.” (p. 34)
Walker speaks of “The Unsearchable Riches of Christ” in the third chapter, and described the glorious riches of Christ. Surveying the book of Ephesians, he shows the reader the “unsearchable” love, grace, forgiveness, wisdom, power, joy, truth, assurance, hope, and mercy in Christ (pp. 38–44). The glorious person of Christ is next to be considered, as the author gives a Christological overview regarding the deity, humanity, agony, and glory of the Savior. The chapter concludes with an explanation of the glorious mystery of the gospel and the revelation of Jesus Christ. “The unsearchable riches of Christ are proclaimed in order that they might be known and enjoyed, received by sinners who have come to rest in the boundless resources of Jesus Christ as their Deliverer, the One given for the very purpose of meeting the needs of fallen people. That in itself is unsearchable!” (p. 48) All other pursuits leave something to be desired, but the knowledge and loveliness of Christ, which is inexhaustible, is satisfying beyond measure.
Chapter four is about the blessed doctrine of adoption. Rooted in the writings of the apostle John, the author presents the breathtaking reality of God’s love towards His children: “This is indeed a love that comes from God the Father, the God who does abiding good to the utterly undeserving, establishing an intimate relation with them in giving, as a gift of love, His own beloved Son. This is a love without measure flowing from the infinite heart of a good and loving God, an ocean without shore, a realm without frontier.” (p. 58) The author shows how the love of God is everlasting and unchangeable, abounding and unlimited, and undeserved and overwhelming. (pp. 58–59) He has given us a new nature and calls us His sons, and Walker beckons us to behold this truth for wonder and encouragement, for trust and confidence, for obedience and fortitude, for joy and thankfulness, and finally, for joy. (pp. 60–65)
Continuing with his examination of the apostle John’s writings, Walker addresses eternal security in chapter nine: “The Jewel of Assurance.” He points to the pastoral mindset of John in his first epistle and how he wanted his readers to know Christ and have life in Him (cf. 1 John 5:13). We see that assurance of salvation is definable, desirable, and possible. (pp. 67–76) The author closes the chapter with the pneumatological reality of assurance: “It is the Spirit of adoption who works in us faith and its fruits, implanting and stimulating graces which are the evidence of new life and witnessing with our spirit to their presence and reality and owning us by His sweet influences and by these means as children of God. The good grounds of confidence in the life of a saved person produce, through the Spirit’s witness, their full gift in our minds and hearts.” (p.77)
In what I see as the most important chapter of the book, “The Marks of God’s Children” seeks to present a framework of the Christian life. The author begins by laying to rest some common “inconclusive indications” of assurance of salvation like visible morality, head knowledge, and external religion. (pp. 80–84). He then devotes the rest of the chapter to showcase the marks of a true Christian. These “indispensable indications” of biblical assurance are repentance and faith, devotion to God, growth in holiness, and love for the saints. (pp. 85–108) This section alone is worth the cost of the book and is a spiritual gem for the newly converted and veteran Christian alike. I will certainly be using this material for disciple-making in the future.
“A Work in Progress” is the title of chapter seven, in which the author surveys the apostle Paul’s writings on sanctification. It is a masterful call to persevere; to press on in the Christian life. We should strive to “work out our salvation with fear and trembling” (Phil. 2:12) and not be passive in our pursuit of holiness. Walker rightly points out that Paul’s exhortation to put on the armor of God (Eph. 6:13–17) “is not a call to occasional endeavor but a command constantly and thoroughly to work at a task until the point of completion.” (p. 113) This is not works-righteousness… the indicatives of the gospel (what Christ has done) are prior to the imperatives of the gospel (what is expected of us). “Our joy and blessing as God’s children,” says Walker, “are bound up in God’s ultimate purpose for us, and he is sovereignly bringing it to pass.” (p. 125)
The final chapter focuses on the apostle Paul’s later writings, particularly those sections where we gain some insight into his impending death. “A Life in Review” is a heartfelt look at the apostle’s unending endurance in the fight and race of the faith. Paul looks around, looks back, and finally looks ahead to a great crown, a great Christ, and a great company of redeemed sinners in the consummation. (pp. 130–138)
Jeremy Walker’s “Life in Christ” is a warm and encouraging explanation on what it means to be a Christian. With pastoral sensitivity and theological clarity, he presents a biblical faithful work on being a disciple and living life to the glory of God. Like a modern-day Puritan, Walker marries doctrine and practice to create a magnificent resource for instructing maturing disciples of the Lord Jesus Christ.
