The Deep Things of God: How the Trinity Changes Everything

Second Edition

By Fred Sanders

... Show All

The doctrine of the Trinity is taught and believed by all evangelicals, but rarely is it fully understood or celebrated. In The Deep Things of God, systematic theologian Fred Sanders shows why we ought to embrace the doctrine of the Trinity wholeheartedly as a central concern of evangelical theology. Sanders demonstrates, engagingly and accessibly, that the doctrine of the Trinity is grounded in the gospel itself. In this book, readers will understand that a robust doctrine of the Trinity has massive implications for their lives, restoring depth to prayer, worship, Bible study, missions, tradition, and understanding of Christianity’s fundamental doctrines. This new edition includes a study guide with discussion questions, action points, recommended reading, and more.

“When faced with dark riddles about our triune God, I turn to books by Fred Sanders for help with seeing the light of Scripture. In this book, deep questions find careful answers in a living theology that breathes and pulses with joy. As Sanders reminds us, God’s inner life, ‘in the happy land of the Trinity above all worlds, is a livelier life than any other life.’ This readable book on God’s undiluted life is fantastically perceptive, and it’s been made more valuable now in a second edition with additional features for personal study, Bible meditation, group discussion, and real-life application. Like never before, The Deep Things of God invites new travelers to hike into the glorious terrain of this happy land together.”
Tony Reinke, journalist; author, 12 Ways Your Phone Is Changing You

“What is already an excellent standard work on the Trinity has just become more useful. Like the first edition of his book, Fred Sanders’s second edition aims to show the astonishingly wide relevance of this Christian doctrine to every area of our living and thinking—but now, with the addition of a helpful study guide, study questions, and other aids, the book deserves the widest circulation.”
D. A. Carson, Theologian-at-Large, The Gospel Coalition

“Sanders has a gift for making the deep things of theology—in this case, the doctrine of the Trinity—clear and compelling rather than shallow and simplistic. This is as good an introduction to the essentially Trinitarian shape of evangelical faith and practice of which I’m aware. Every evangelical should be able to explain how the gospel is Trinitarian and the Trinity a summation of the gospel, and Sanders shows us how. He makes a convincing case that there is nothing wrong with the evangelical church in North America that a good dose of Trinitarian theology, if absorbed into the bloodstream of the body of Christ, could not cure. So take, drink, and prepare to be edified.”
Kevin J. Vanhoozer, Research Professor of Systematic Theology, Trinity Evangelical Divinity School

“‘The Trinity’ is not just a doctrine to which the church gives formal assent, nor is it one doctrine among many. It refers to the God who exists eternally and has created and redeemed us, the God of our trust and love, to whom we offer our worship and lives of thanksgiving. There are well-informed books on the Trinity and many accessible ones—but these characteristics don’t always converge in the same volume. They do in The Deep Things of God.”
Michael Horton, J. Gresham Machen Professor of Systematic Theology and Apologetics, Westminster Seminary California

“Sanders’s book should be required reading for anyone involved in the work of the gospel. It will help readers catch a fresh vision of the depths of the message they strive to proclaim and foster a renewed sense of the grandeur of the Christian life they invite people to enjoy.”
Mark Hopson, President, National School Project

“As it is with other biblical truths, I’m often asked by people about the Trinity, ‘Does it really matter?’ One might conceivably respond by saying, ‘Apart from the truth of the Trinity, nothing else does!’ If that sounds like an overstatement, this book is precisely what you need. If you’ve been puzzled by the assertion that God is one divine being who subsists in three coequal persons, this book is precisely what you need. If you want to understand how the reality of our triune God affects every dimension of Christian truth and life, this book is precisely what you need. It is remarkably accessible, altogether persuasive, and urgently needed in today’s church. I’m thrilled to see it released in a second edition. If you missed it the first time around, don’t let it happen again. I can’t recommend it too highly.”
