This is a good book. It's very deep though (at least for me) and I would suggest you read it slowly.
John Bevere does a good job with this book. It includes a lot of Scripture (which I love) and brings about a reminder to believe ALL of God's Word and not just the parts that we deem ourselves "worthy" to believe.
I haven't finished it yet because there is so much information and quite frankly my faith has been very challenged to believe some of the things that are plainly put in Scripture and that John further talks about.
If you want to go deeper in your faith then this book is a good start. I would recommend it for anyone who wants to stop half-way believing God's promises and wants to cling to all of them whole-heartedly.
