The new book From the New York Times best-selling author of Real Marriage

Who Do You Think You Are? is an exploration of the issue of identity and an encouraging examination of what it means to be “in Christ.”

Drawing from nearly two decades of pastoring, Mark Driscoll knows that underlying most individuals’ struggles in life is the issue of their identity. “The fundamental problem we have in this world,” he says, “is that we don’t understand who we truly are—children of God made in his image—and define ourselves by any number of things other than Jesus. Only by knowing our false identity apart from Christ, in comparison to our true identity in him, can we finally deal with and overcome the issues in our lives.”

Who are you? What defines you?
What is your identity?

How you answer these questions affects every aspect of your life. So it’s key to get the answers right.

In Who Do You Think You Are? Pastor and New York Times best-selling author Mark Driscoll helps you to explore the answer to these questions by exposing common misunderstandings while leading you to discover who you are in Christ

Whether you are someone who is spiritual and curious about what it means to practically live as a Christian, or a Christian wanting to figure out what it means to live out your identity in Christ and experience real joy and freedom, you’ll enjoy Who Do You Think You Are?

What others are saying

“Mark Driscoll is a gifted teacher able to make complicated spiritual truths easy to understand and apply in our lives. In Who Do You Think You Are? you will be transformed by the truth that we are made in the image of God. And this isn’t just an abstract theory to think about—it’s a practical reality to live by.”

“Finally someone has given the foundational and transformational subject of gospel identity the thorough treatment it needs. Jesus didn’t just forgive your sins—he gave you a brand-new, life-altering identity as well. Every human being assigns to himself and lives out of some kind of identity. In this very helpful book, Mark powerfully addresses both our identity idolatry and our identity amnesia. I am very thankful for this book and soon you will be too.”

Paul Tripp
Author and speaker

“I am very pleased with Mark Driscoll’s latest book, Who Do You Think You Are? Normally that question makes me start guiltily, but in this case, Driscoll is simply unpacking the ground of every believer’s identity from the book of Ephesians. Many people will be enormously helped by this book.”

Douglas Wilson
Pastor, Christ Church

“This book hits very close to home for me. I spent years in ministry for Christ without understanding my identity in Christ. I know now that I was not alone. When we place our identity in anything but our relationship with Jesus, then we have built our future on a platform that could crumble at any moment. But when, by the grace of God, we understand who we are in Christ, everything else can crumble and we will still be standing. I highly commend this book to you.”

Sheila Walsh
Speaker and author, God Loves Broken People

“The key to understanding your true identity is shaped by your relationship with Jesus Christ. ‘In Christ’ you are completely acceptable, extremely valuable, eternally loved, totally forgiven, and fully capable. Pick up a copy of Who Do You Think You Are? and learn the truth about who you really are.”

Rick Warren
Pastor, Saddleback Church
Author, The Purpose Driven Life

“'Who do you think you are?' is a far-reaching, belief-revealing, life-shaping, and identity-forming question. My friend Mark Driscoll is an exciting new voice speaking to a newly-minted generation of men and women who are hungry for spiritual truth today. Who Do You Think You Are? brings us insights from ancient history that speak to us powerfully today. Mark unpacks truth that every believer, young and old, needs to know. I highly recommend this book to you.”
