Nobody likes to be bored. No one comes to church just hoping that the sermon will be mind-numbingly dull. You want a preacher who is both serious and lively. You want one who refuses to be dull and boring.
This means he needs to be a man who is never bored by the gospel but who is persistently passionate about Jesus. Would you pray for me?
Here is one of the best bits from one of the best books about these things.
Martyn Lloyd-Jones Preaching and Preachers
I refer to the element of ‘liveliness.’ This underlines the fact that seriousness does not mean solemnity, does not mean sadness. The preacher must be lively; and you can be lively and serious at the same time.
Let me put this in other words. The preacher must never be dull, he must never be boring; he should never be what is called ‘heavy.’
This is to me a very serious matter; there is something radically wrong with dull and boring preachers. How can a man be dull when he is handling such themes? I would say that a ‘dull preacher’ is a contradiction in terms; if he is dull he is not a preacher. He may stand in a pulpit and talk, but he is certainly not a preacher. With the grand theme and message of the Bible dullness is impossible. This is the most interesting, the most thrilling, the most absorbing subject in the universe; and the idea that this can be presented in a dull manner makes me seriously doubt whether the men who are guilty of this dullness have ever really understood the doctrine they claim to believe, and which they advocate.
