Beloved, I did not sit down to write this book because my hands were idle. I sat down because I have seen a hunger in the hearts of God's people, a hunger that is not being fed.

Week after week I stand before a congregation and open my mouth to preach. Week after week I travel from place to place, ministering wherever the Lord sends me. And in all of it, I keep running into the same wall. People know the name of Jesus. They sing about Him on Sunday. They call on Him in prayer. But when the storm rises, when the enemy comes in like a flood, something painful is exposed: many believers are fighting with a name they have never understood, representing a Person they have never truly known.

You remember the sons of Sceva in the book of Acts. They heard Paul preach about Jesus. They picked up the name the way you might pick up a formula. They thought the name alone would do the work. But the evil spirit looked at them and said, in effect, "Jesus I know, and Paul I know, but who are you?" And that spirit turned on them, beat them, and sent them running out of that house naked and bleeding. Their problem was never that the name of Jesus lacked power. Their problem was that they did not know Him. They had a name without a relationship. Religion without revelation.

That story will not let me rest, because it is not locked away in the first century. I see it walked out in church pews and altar calls every single day.

This book is my attempt, by God's grace, to change that in you. I am taking you beyond the name and into the Person. I am taking you from knowing about Jesus to knowing Jesus, until the Jesus of the Gospels, the Jesus who walks through the book of Acts, the Jesus who stands glorified in Revelation, becomes so real to you that your life is never the same again.

I need you to understand what this book is not. It is not a theological textbook, though you will find sound doctrine on every page. It is not an academic exercise, though your mind will be stretched. This is a pastoral letter. It comes from a man who has spent more than a decade in the pulpit, weeping at altars, praying through long nights, watching a truly known Jesus transform lives that nothing else could touch.

I have built this book around three great questions. Who is Jesus in His divine nature? What does His name mean, and what does it carry? What has He done, and what is He still doing? Answer these from Scripture, receive them by faith, and your life will never look the same.

So read slowly, friend. Keep your Bible open beside these pages. Give the Holy Spirit room to speak to your heart as you go. And by the time you turn the last page, I am persuaded you will not merely know about Him. You will know Him.

This is Jesus. This is who He is. This is what He has done. And this is who He longs to be in your life, starting today.

To Him alone be all the glory.
