Of all preaching in the world (that speaks not stark lies), I hate that preaching which tends to make the hearers laugh, or to move their minds with tickling levity, and affect them as stage-plays [read: Hollywood, Carrey, Leno, SNL] used to do, instead of affecting them with a holy reverence of the name of God. (The Reformed Pastor, 119-20)A word for Sunday School teachers, small group leaders, preachers, hospital chaplains.
It is not impossible for 'holy reverence' to co-exist with humor. But it is hard.
Note: by 'levity' Baxter does not mean joy. Laughter is often the substitute for, not the manifestation of, joy.
