The other part is this reality: looks do count. We might claim that it shouldn't and preach that transformation is, as we say (in "the rooms"), an inside job; that, too, is true. Still, there's a lot to be said for changing external manifestations of self to generate engagement with Self and others.
What if churches provided free hair styling and a thrift store/consignment shop shopping trip to those in need?
We could call it an outward and visible sign of an inward and spiritual grace.
