There is no need to be longwinded as a pastor, but there is a difference between being longwinded and preaching for a long time. Preachers should be conscious of time because God does everything in decency and order; nonetheless, God's word is not on the clock!
I am growing more and more aware that all too often we preachers aim at nothing and hit it.
I am suspicious of writers who go looking for issues to address. Writers are neither preachers nor journalists. Journalists know much more than most writers about what's going on in the world. And if you want to change things, you do journalism.
My experience in relation to taking on the preachers of hate was saying to them it's compatible being British, being Western, being Muslim.
