Ben Greenfield is known as a health enthusiast, and one of America's leading personal trainers. He is also a so-called biohacker and digs deep into how to live a healthiest possible life. A couple of months ago I started reading through his large and long health book; "Boundless", and since it is as long as it is, I thought it would be rewarding to read a shorter book in the meantime by the same author. Before starting readng this one I knew he was a Christian and from "Endure" you get a good insight into his Christian lifestyle, his views on different topics and how he e.g. compares physical endurance with spiritual endurance.
What I also like about Greenfield is that he is honest and speaks straight from the heart and perhaps with a use of words that may be considered a little over the edge by other more conservative believers. The book can seem to be written in a more "talking" way and it can seem somewhat fragmented at times, even though it deals with a relevant topic in each chapter.
For some, his use of writing can be somewhat confusing. He uses regular font in black and red, but also several italic paragraphs in both red and black. On the whole, I liked his style, and the fact that he is so clear about the spiritual life, and what as believers will face in the spiritual battles he describes. This is a book that deals with slightly different everyday topics and connects them to the main theme which is endurance in the Christian life; themes such as prayer, lust & desire, sex, self-control, marshmallows (the test), the golden rule, temperance, flow, death, hell and much more. In addition, he comes with several book tips and other references. He also constantly refers to his book "Fit Soul" which seem to be about something in the same category as this one. I've not yet read "Fit Soul", but I got it available as an e-book.
What I reacted a little critically to was, among other things, his view on heaven. He believes that heaven is ultimately an eternity on a new earth, and he tempts, especially the non-believers, with how much earthly things can be done on this earth, such as reading all the books you didn't get to read on the old" earth and everything else you didn't have time to do during your short life on this earth. Unfortunately, the focus was on earthly things on this topic on heaven, and not on meeting Jesus face to face on this new earth (heaven) he believes in. Furthermore, there was a slightly exaggerated focus on "sinners prayer", as if there were some magic words one could utter to be saved. But he does not hide the fact that one has to mean these words from the deepest of one's heart.
Apart from this, there may have been a few other small things I stumbled across, but mostly the book is radical to be written by someone from the American fitness industry. I also like Ben's down-to-earthness and simplicity, and his focus on a healthy family life. We often tend to complicate the spiritual life, but Ben tries to give it direct relevance to our ordinary everyday life with several useful and concrete tips, while also challenging both believers and non-believers all the way through the book. Read this if you are interested in a slightly different Christian book than the standard ones you get in a Christian bookstore.
