We are working through the Acts of the Holy Spirit through the Apostles just now. Got through Acts 1 pretty well; in Acts 2 now for three weeks with no real end in sight.
I still do a sermon list in advance, text and proposed title, for the worship team and the presentation is still Biblical in nature.
I get a sermon manuscript ready for each Sunday morning and a sermon manuscript or brief for Sunday night, which we still do. I try to do at least a sermon brief for Wednesday night.
I dont spend as much time on the web as some seem to say but I do look for stories and images to touch strings. We used to do it with books and magazines and papers; now we have the web. I dont go to other guys sermons much (ever) or to illustration services. I am not a good consumer. Very much concerned with original production.
Sermon prep is quicker than it used to be but it is still vital. Dont get up to do stuff off the cuff, guys and girls.
