I've been sharing about how I tend to preach without notes. Of course I take notes when I'm studying to prepare for my sermon. I write out a lot of information. Then I'll usually do a run-through of my sermon to get a sense of what I want to say. I may refer back to the notes in this process. Then I'll take and put together my visuals to support and emphasize my message. Then I'll go through the sermon one more time with the visuals in place to make sure everything fits.
For me, running through the sermon as if I'm preaching it to the church is the best way to get a sense for what I want to say and how I want to say it. But preaching without notes leaves room for the Holy Spirit to step in and divert the sermon to a different point or direction than I originally intended.
How do you make room for the Holy Spirit while you preach?
