Here’s a link to a Mark teaching series that Dr. William L. Lane led at Christ Community Church in Franklin, TN in 1998. He’s the author of the commentary pictured at right, one of the best for the Gospel of Mark. (Click on the image to look inside the book at Amazon.) From the By/For site:
This Mark teaching series is led by Dr. William L. Lane, author of The Gospel According to Mark from the New International Commentary on the New Testament series. This series was the final time Dr. Lane lectured on Mark.
The study page includes a pdf file of class notes and 13 lectures by Dr. Lane. See it all here.
