I have a confession: I have a standing bias against any book which has the word ‘essential’ in the title. I have several ‘essential’ books on my shelf, but I always think, “Essential? Really? I don’t know how I have made it this far in life without cracking open The Essential Schopenhauer or referencing often my copy of Lawrence Quirk’s essential biography of Joan Crawford.” Of course I am using the term essential narrowly. What authors (and publishers) have in mind is a distillation of the ideas, elements and basic characteristics of their subject. Even this doesn’t put me at ease because I always wonder what is being left out of such ‘essential’ descriptions and compilations.
My standing bias aside, I picked up Robbie Castleman’s New Testament Essentials because I have read her work appreciatively before (even reviewing a couple of her books here). Castleman is professor of biblical studies and theology at John Brown University in Siloam Springs, Arkansas. Her previous works include a go-to-resource for parents wishing to shepherd their children through Sunday morning worship and pass on the essential aspects of the Christian faith (the book is aptly titled, Parenting in the Pew). Last year she released Story-Shaped Worship which delved deeply into the overarching biblical story and Christian history to help worship planners and liturgists enrich their Sunday services. Both books are on my essential reading list.
New Testament Essentials: Father, Son, Spirit and Kingdom is part of a series from IVP which includes Greg Ogden’s Leadership Essentials, Discipleship Essentials and The Essential Commandment, Daniel Myers’s Witness Essentials and Tremper Longman’s Old Testament Essentials. I own three of the other volumes but have yet to work through any of them ( I’m still trying to figure out if that’s really essential). So Castleman is my introduction to the series.
I have really enjoyed the twelve studies which she presents. In each of the studies she is sensitive to the operation of the Trinity, the outworking of the gospel in the church and the full in-breaking of God’s kingdom. The studies are organized into three sections. Part one examines the ‘revelation of God in Jesus Christ’ and focuses on Bible passages which explore Jesus, life, teaching, death, resurrection and the implications for us would-be-followers. Part two focuses on the ‘indwelling of God by the Holy Spirit in the church.’ These studies (study 6-8) explore how the Spirit’s presence binds believers to one another in counter-cultural ways. Part three examines the ‘present and coming Kingdom of God.’ This final section reflects on how citizens of Christs kingdom ought to love and serve one another and how our faithful witness to Christ is galvanized by our sure faith and hope of his return when creation and humanity is restored.
