Query: Relevant Facts and Diagnosis

Barna's surveys and studies provide church leaders with a dependable source of diagnosis. Barna's expertise lies in his ability to pinpoint exactly what is happening.I place much trust in Barna's ability to diagnose. His suggested solutions, however, I disagree with. We can offer teaching to our people, for instance, but what do we do with all the people who claim to be believers but yet refuse to excercise their minds?My advice: read Barna to diagnose, that is his specialty. The treatment, that lies elsewhere, perhaps as a combination from Os Guiness in "Fit Bodies, Fat Minds," Gene Getz's classic, "Sharpening the Focus of the Church," and even the secular, "Bowling Alone" by Robert Putnam.
