Maybe you’ve found this site already but I was not aware of it. Paul Schafer has done a wonderful job of gathering links to mp3 sermon files for the best preachers and theologians alive. I was encouraged to see how many links he has there that I have not come across. Of special interest are the Links to Carl Trueman’s lectures from various sites. Paul has a great section on Cross centered preaching links. You can access his site here. Enjoy.
