Here’sa glimpse into the sausage factory of expository preaching. Recently my commitment to consecutive exposition was acutely tested. I tackled the chapter every seminoid dreads from the day he graduates, namely Leviticus 15 (you know, the heart-warming one about emissions and discharges of various bodily fluids).
