Radical by David Platt is a great book. David looks at the American Christian way of life and compares it to the truths of scripture. He examines the ways in which modern day Christianity has greatly derailed from that of earlier Christians... David does seek to make his reader feel good, but rather, he seeks to expose his readers to truth. Even when that truth is hard to hear.
This book will challenge you to your core. It will make you question what you believe, why you believe it, how you live, how you spend your free time, and on and on i could go. If you are frustrated with "American Christianity" and the scriptural contradiction therein, or if you are interested in really growing deeper in your faith - this book is for you!
