Dr. Tripp has made a brief but intriguing video introduction to the book that would be worth your time to watch. You can also read the first chapter for free here.
Here are some comments about the book from Dr. Tripp's website:
Is Christ the center of your life?Is He really your source, your motive, your goal, and your hope?
Is it possible that your Christianity may, in fact, exclude Christ?
“There really is no place for Christ in many people’s Christianity. Their faith is not actually in Christ; it is in Christianity and their own ability to live it out.”
Paul David Tripp expertly traverses the deepest recesses of the human heart and compassionately invites fellow Christian travelers to journey with him into God’s bigger kingdom. The author promises readers that they will be encouraged, excited, and motivated by hope as they learn how to set aside their “little kingdom” attachments which can expertly masquerade within the church as Christian activism, legalism, emotionalism, formalism, creedalism, and externalism; in favor of God’s expansive and soul-freeing eternal quest.
Tripp demonstrates through sound biblical principles how humanity is made by God to transcend far beyond the mere physical realm and is likewise created to be “glory junkies”—those whose visionary lives are governed by God’s grand purposes rather than existing only within their narrow self-interested confines. Writes the author, “It is a fundamental denial of your humanity to narrow the size of your life to the size of your own existence, because you were created to be an ‘above and more’ being. You were made to be transcendent.” Tripp then shows Christians how to “transcend” through daily, moment-by-moment, practical methodology that transforms individuals into the image of Christ.
