Some background on myself: I'm an old-school hard-shell Baptist. I'm used to small churches (typically no more than 150 members or so). 13 Years ago I announced my calling to preach God's word. I have not attended seminary, though I am not opposed to it. I have no problem in learning history and language, though I do not like the idea of someone trying to tell someone else how to preach.
I recently came across a blog that purported to teach men how to preach without notes, if necessary. For my own experience, this was a foreign concept. I've never preached with notes. I pray and study the scriptures, then mark the place I feel the Spirit leading me to...but I'm going off on my own tangent here...
I use notes. I have to because my background is in teaching, where I have more latitude and more time to get to the point. So, if I don't, I have a tendency to ramble.
This blog also stated some tips for preachers. Among its various tips were the following:
1. The preacher should stay behind the pulpit and not move.
I move around, but not too much. I can't stand preachers who walk around like they're performing.
2. The preacher should not raise his voice. Use microphones to be louder.
It's not always about being louder. We don't speak in a monotone and raising and lowering our voice can be for emphasis or demonstration.
3. Publish a version of your notes either on a screen or a flyer for the congregation.
It depends on the sermon and what the notes are.
4. Always prepare a message that relates to current events in your church.
5. Always prepare a message relevant to any possible holidays/occasions.
Topical preaching has an important place, but I believe the emphasis should be on expository preaching.
