Mark Dever‘s latest 9Marks interview is available for free downloading:
“Biblical Counseling with Ed Welch”

I highly recommend Dever MP3s. They are first-class: always interesting and biblically informed. And the interviews are lots of fun!

1. 60 other MP3s (mostly interviews)
2. over 60 Carl Henry Forums MP3s
3. 25 “bonus talks”
4. over 600 sermons (mostly by Dever)
