I found some short videos under the LLoyd John Ogilive Insitute of Preaching series, where Johannine scholar and George Eldon Ladd Professor of New Testament at Fuller Theological Seminary, Marianne Meye Thompson discusses subjects such as the relationship between preaching and scholarship, a memorable sermon she recalls, and other items. In particular, I want to draw attention to the three videos where she discusses John's Gospel.
The first is the subject of inspiring Johannine texts:
The second considers some of the challenges of preaching John's Gospel:
And the third discusses John's Gospel in relation to the Trinity
All of her videos in this series can be viewed on this page. Enjoy!
