I picked up this book because I was looking for a "front end" to a disciple-making program for my local church. I found a few things I can use. While Barna's passion is well-founded, he chooses to make the same arguments that has lead to a spiritual dichotomy: 84% of American's claiming a "Christian" faith while our society and culture crumble. It seems we have the evangelism part down, but we lack the proof that what we preach works in our own lives. (Barna briefly hits on "disciple-making" in this book and goes on to write a great book on the subject, "Growing True Disciples"). If the energy and resources put into evangelism were put into disciple-making, Christianity would have a profound impact on ourselves, our families, churches, neighborhoods, and world. Barna doesn't make this argument, so I my opinion, this book falls short in identifying "Evangelism that Works".
