The Most Important Question You Will Ever Answer There is a name that makes demons tremble. A name that heals the sick, breaks every chain, and opens the door to eternal life. But do you truly know the Person behind that name? In JESUS: Who He Is, His Name and Finished Work, Pastor John Onyekachi takes you on a transformative journey to discover the most extraordinary Person who has ever walked this earth. This is not just another book about Jesus. It is an invitation to move from knowing about Him to truly knowing Him. Through 25 powerful chapters, this book unpacks: Who He Is — His divine nature, His genuine humanity, His eternal existence as the I AM, and His oneness with the Father His Name — The authority, power, and revelation packed into the name above every name, and why knowing the Person behind it changes everything His Finished Work — What He accomplished at the cross, what He is doing right now at the right hand of the Father, and what He will do when He returns With pastoral warmth and scriptural depth, Pastor Onyekachi addresses the critical difference between using His name as a formula and living in genuine relationship with Him. He confronts the story of the sons of Sceva—men who had the name but not the relationship—and shows you how to avoid the same tragic mistake. Whether you're a new believer, a growing Christian, or a minister of the gospel, this book will deepen your love for Jesus and anchor your faith in the unshakeable reality of who He is.
