The Prayer of Jabez: Breaking Through to the Blessed Life is an inspirational book published in 2000 by Bruce Wilkinson as the first book in the "BreakThrough" book series. It is based on the Old Testament passage 1 Chronicles 4:9-10.
Jabez called on the God of Israel, saying, Oh that you would bless me indeed, and enlarge my border, and that your hand might be with me, and that you would keep me from evil, that it not be to my sorrow! God granted him that which he requested. (WEB)
In the book, Wilkinson encourages Christians to invoke this prayer for themselves on a daily basis:
I challenge you to make the Jabez prayer for blessing part of the daily fabric of your life. To do that, I encourage you to follow unwaveringly the plan outlined here for the next thirty days. By the end of that time, you'll be noticing significant changes in your life, and the prayer will be on its way to becoming a treasured, lifelong habit.
The book became an international bestseller, topping the New York Times bestseller list[1] and selling nine million copies. It received the Evangelical Christian Publishers Association Gold Medallion Book of the Year award in 2001.
