Sermon prep is difficult work. It’s long, arduous, and tedious. Because of the difficulty inherent to prepping a gospel-centered, culturally-intelligible, Biblically-saturated sermon, many opt for other types of “sermons.” Some preach creativity.
Some preach comedy.
Some preach social observations.
Some preach practical pep-talks.
It’s simply easier to “preach” these other things than it is to open God’s Word each week, find a fresh sermon for God’s people, and put spiritual food on the table.
