I'd like to make the argument that Living Inside the Bible (Belt) is both limited and expansive. Carter makes several references on connecting with the students on some kind of Christian empathy but comparatively, I'd like to make the point that these students sound like any faith based student/individual/person I've met. And like Gina points out, Academia is a clash of faiths. My argument though is that everyone has a faith in something. And I am not speaking spirituality or religiously. Just faith. Faith in thy self, faith in money, economic Marxism, socialism, the good of people, the bad within the system, that the world is against them, that they're capable of anything, that school is the answer, that school is not the answer...and so and so forth...
And in such, many a time there is a resistance when these individuals hit academia which (due to poor teaching strategies and a broken academic system) requires that they surrender their general life-styles to worship among books and a voice that they're not accustomed to. The only difference in this scenario is that the Christian Bible holds a rules of etiquette for society that are both strict in their adherence and of such varying opinions that they're bound to clash with academia at some point of time. In any event and any variation of faith, rhetorical dexterity is the key. Connect, validate, let a person have a voice and then the skills that you need to teach them can be taught.
