I really appreciated this book and it's slightly different, but very important, take on discipleship. Over the course of the book he describes the importance of a "heart focused" discipleship that not only teaches knowledge about the Bible and our faith, but helps us recognize the tactics of our very real enemy and the authority and power we have to resist him. My favorite take away was his "WLVS" acronym for one of the ways the enemy gains ground in our lives and eventually, if not resisted, can gain a stronghold that feels impossible to break (but is!). W=wounds, L=lies, V=vows, S=strongholds. His suggestion is that when we are wounded (by things done TO us or by wounds of absence/neglect), we begin to believe the enemy's lies and begin to "agree" with them as truth (ie: "If my dad doesn't love me, how can any man love me?" or "If my friends abandoned me I must not be _____ enough"). As those lies become our reality, we consciously or unconsciously make vows (often of self protection..."I won't ever again let a man hurt me" or "No one is ever going to make me feel out of control again" etc). As we live out these vows, they often steal, kill, and destroy our relationships, joy, and ultimately, our freedom in Christ as they become strongholds that dominate our lives.
Over the course of the book he describes how heart focused discipleship in community with others can help us to recognize those wounds and begin to remove and tear down the lies, vows and strongholds we've handed over to the enemy so we can all begin living in the true freedom that Jesus promised throughout the gospels. It's a very practical, easy read and I'd highly recommend it.
