Undressed: Taking Everything Off and Putting on What Matters Most

by Mark Cornelison

“Sometimes, just when you think life is going just the way you expect, things can change. What once was normal and acceptable is replaced by a sense that there is a better life to be lived, often in surprising ways. This describes Mark Cornelison, contestant on NBC’s The Biggest Loser, before his life-changing experience on this popular show.

Mark realized that the life he was living had to look different and he gave God the freedom to, not only change him physically, but also mentally, emotionally, and spiritually as well. This new chance to live life brought with it a message that he knew could change other people in the way it had changed him.

The world he had complicated with stuff, that we all think is important, was taken away one layer at a time. He was then clothed with a new, simple life. Now he shares the story and challenges you with what he has learned from the journey.

Come see what needs to be taken off of you so that a better you can truly live.”

“Even though millions of fans of The Biggest Loser know Mark from his epic role in an epic season of the show, the “back story” of Mark’s journey overshadows anything that happened in front of the camera. The story-behind-the-story is about a God who relentlessly pursues us, and will use anything—including a weight-loss reality show—to strip away the lies we live by, creating a hunger for Him instead. And then He offers Himself, and His truths, to fill that void. Read Mark’s story, and you’ll find what you’ve always been looking for.”

“One of the most freeing things to do in life is to replace the lies we tell ourselves with the truth that comes from God’s Word. Mark captures this freedom in this refreshing, raw, and authentic book. This book encourages the Church to be living proof that God matters and people matter. And when we live out this truth, we can impact people with Mark’s own words, “Do what you need to do today to be the person you are meant to be tomorrow.”

— J. Chad Barrett, Director of Child Evangelism Fellowship, Houston, TX, and founder of IEWorks, LLC.

“No one likes to be exposed, literally put on display for all to see…especially in front of a large audience. I would often joke with Mark about how terrifying that must have been on The Biggest Loser. However, exposure is what all of us need as we struggle toward the authentic life that Christ desires for us…”

— J. Roger Davis: President of Student Life, Birmingham, AL

“It is rare in the world that we live in to find someone doing something without ulterior motives. We not only expect it, we look for it. Mark writes this book out of a selfless desire to use his experiences and knowledge to share tools that will help bring healing, health, and deeper, richer relationships to others. This book is as authentic as Mark himself.”
