If only there were more powerful preachers like W. A. Criswell. For 55 years Criswell pastored First Baptist Church of Dallas, Texas. The Criswell sermon library is a searchable database, which is a bit clunky to navigate, but well worth the trouble. I would like to see them organize some pages by series or Bible books.
Not all sermons have media, and unfortunately the audio content is all streaming Windows Media files. Nevertheless, it’s a great resource to have this preaching giant on hand.
