The final P's of a sermon

I'm going to be preaching in a few hours and, having typed up what I'm going to say yesterday, I emailed the transcript to myself with the three final P's as the subject.

Polish.
Practice.
PowerPoint.

Polish - Go ever everything with a clear mind and fresh eyes, tweaking what needs to be fixed.

Practice - At minimum, be able to nail your introduction, stories/illustrations, transitions and conclusion. I find this happens after three to five solid dry-runs.

PowerPoint - Only once you've decided the input and flow of the sermon do you look for pictures which communicate the same things in as few a words as possible.
