Anyone who has preached to different congregations, and engaged in pastoral ministry with different kinds of people, will know only too well that the moment when a very particular situation presents itself is precisely the moment when you need to draw deeply on something very central and non-negotiable. One might almost formulate a general rule that the more specific the situation, the more what is needed is a return to core truth, however freshly stated.
