I had been impressed with his printed works, but then I heard a lecture he presented to The Veritas Forum gathering at Harvard University (download the audio: "Is Jesus Christ Truth for the 21st Century?"). I was struck by his gracious tone and comprehensive understanding. He was especially good during the Q&A. Students asked their questions and he responded with the patient wisdom that only comes from a long life of faithful devotion.
The Protestant Church across the world is better for having had John Stott as one its members and leaders. He will be missed.
My 5 favorite books by John Stott are:
5) Essentials: A Liberal-Evangelical Dialogue (with David L. Edwards)
4) Between Two Worlds: The Challenge of Preaching Today
3) Baptism and Fullness: The Work of the Holy Spirit Today
2) Christian Mission in the Modern World
1) The Cross of Christ
Here's a short biographical video about John Stott (Christopher J. H. Wright is the narrator):
