I just got an MP3 player, so I started looking around for a place that has sermons on mp3, so I could listen at work and/or home. I stumbled upon www.sermonaudio.com, which has almost 100,000 sermons, organized by speaker, topic, series, etc. Very cool, for those who would be interested. As I browsed through the speakers listed, I noticed many Presbyterians, many Baptists, some Reformed, and a smattering of others, including missionaries and Campus Crusade for Christ staff. Definitely recommend!
