Brilliant quote from Colin Morris, quoted in Jonathan Lamb's super book "Integrity":
It is not from a pulpit but a cross that power-filled words are spoken. Sermons need to be seen as well as heard to be effectual. Eloquence, homiletical skills, biblical knowledge are not enough. Anguish, pain, engagement, sweat and blood punctuate the stated truths to which men will listen.
Enough said.
