I have been reading the internet monk lately and i really liked his series on sermons.

It got me thinking about what I would say about sermons. A list of tips for the new preacher:

1)If you find the material boring so will your listeners.

2)Don't think that a sermon of longer than 20 minutes in riveting, it isn't.

3) If you tell a joke make sure it's funny.

4) Repetition is an overused rhetorical device.

5) Repetition is an overused rhetorical device.

6) Assume your audience can read, don't insult them by simply retelling a bible passage.

7) No one cares who begat who, so make your choice of a text relevant.

8) Not everyone left school in year 2 some even went to university.

9) Don't assume you know more than your audience or you may get a shock.

10) This is not a chance to argue for your position or ideas.

11) This is not a chance to insult, belittle, or simply talk down to people you don't get on with.

12) A sermon that takes 5 minutes to put together sounds like a sermon that takes 5 minutes to put together.

13) Do the research, nothing is more annoying to a listener as being told things you know are wrong.

14) God is not speaking through you, you are sharing your ideas, so don't act like a divine prophet.

15) Dress well, it is an insult to those listening to dress poorly.

16) Midnight Saturday is not a great time for sermon preparation.

17) Repetition is an overused rhetorical device.

18) Quit while your ahead, leave the listener wanting to hear more not bolting for the exit.

19) Don't be afraid to ask the audience to think for themselves, it might give them a nice surprise.

20) ???

Any suggestions.
