Every hack is grounded in the homiletical tradition, from Fred Craddock's inductive preaching to the New Homiletic to the Black preaching tradition, then translated into steps you can test in your next sermon and evaluate afterward.
Hacks is built for the solo pastor with no staff, the bivocational minister writing sermons between shifts, the lay preacher filling in for the first time, and the seasoned preacher who knows something has gone stale and can't name it.
Pick one hack. Try it Sunday. Tell me in the comments what happened.
