Whether you are a new Christian, or have been for a while and feel in need of a refresher, or have been around church for years but things have only just clicked into place for you, this inspiring and practical book will give you the essentials—what you really need to know if you’re going to follow Jesus.

Gary Millar shows readers how letting the fundamental truths of the gospel take root in our hearts changes everything about the way we see God, ourselves and the world around us. He explores what this miraculous change on the inside looks like on the outside as we live our lives shaped around gospel priorities.

Packed full of warmth and wisdom, this book will set anyone up for a lifetime of living for Jesus. It's perfect for giving to new Christians and makes a great gift for baptisms or confirmations. Mentoring questions are included for each chapter, so it's also an ideal resource to use in one-to-one discipleship with younger believers.

I thoroughly enjoyed this book. Gary Millar has given us that rare combination, an accessible book written in a warm, engaging, realistic style but with content that has a depth arising from a thorough and thoughtful biblical and theological understanding. It will be a thoroughly useful book and I commend it warmly.

Because more and more people who come to genuine faith in Christ have little or no Christian background, it is becoming more and more important to orientate them to Christian life and thought. What is needed is something of a cross between a gentle introduction to basic Christian belief and a ‘how-to’ manual. This book is it.

Nancy Guthrie

Author; Bible Teacher

In this engaging little book, Gary Millar is able to communicate, with good humor, colorful illustrations, and biblical faithfulness, the most significant truths a person needs to know to live out the Christian life. I anticipate giving plenty copies of this book away to people wanting to understand the basics of life in Christ.

“Thorough, concise, engaging, helpful for those both old and new to Christianity.”

I was looking for a book to share with others new to their faith in Christ. This book drew me in right away, not just for others but for myself. It is thorough, concise, clear, true to the gospel, and engaging. I would recommend this book for anyone, old or new to the Christian faith, as well as those exploring. It always left me wanting to read more. 6 short chapters, recommended resources, and mentoring questions make this an accessible and helpful tool for use in groups or one-to-one discipleship.
