I recently read "Greater" by Steven Furtick and was impressed overall, with some minor caveats.
First, you should know that the basic premise of the book is living the life of doing "greater things" that Jesus talked about, but not about becoming "great." Furtick notes that this life that Jesus has called us to will not necessarily lead to great praise from world leaders. Instead it's a call to fully live the life that God has called us to through walking WITH HIM.
Second, I want you to know that I have some serious issues with a lot of books like this that promise great things in our lives and don't really want to talk about sacrifice and effort. This book, however, was able to overcome those with good use of Scripture and honesty about the author's life. This is not a book that says, "I'm doing it all right and you should copy me and you'll become great." This is ultimately a book about following God.
Finally, I want you to know that this book will challenge you and inspire you. I know those may sound cliche, but they are true, if you are able to overcome some of your own trepidation of "name-it-claim-it" speakers and authors. Furtick is not one of those people and doesn't come across that way in this book...as long as you read it with an open mind.
Overall, this is a good book with some real challenges from scripture and real-world application written in a relevant and relational manner that I would recommend to most Christians.
Please note that I received this book for free from Waterbrook Multnomah in exchange for this unbiased review.
