I am not saying anything about any recent books here...but I think this reminder, from Stephen Altrogge, is important:
"...for most of us, being radical for Jesus means being faithful to do the 'ordinary' Christian things. The Christian life is inherently radical, inherently risky, and inherently crazy. Following Jesus means dying to myself every single day. That is radical. If I seek to obey God's Word, my life will look very different than the rest of the world."
