The snub nose
This sermon shape starts from as broad a base as possible. From a variety of sources, both biblical and contemporary, it draws people in. As it progresses, it appears to draw towards a challenging and incisive conclusion. However, just before that happens, it loses its nerve, and flattens out into a harmless and blunt end. It has the advantage of capturing people along the way, and avoids the pitfall of leaving people smarting from a sharp conclusion. However, it never quite reaches its point. What do you think?
Look out for the splotch and the broken arrow later today.
