Last Christmas, I read a biography, Basic Christian: The Inside Story of John Stott, by Roger Steer. I found it helpful, encouraging and challenging. Stott was someone who loved Jesus, loved the Bible, was a humble leader of integrity, and had a particular concern for the Majority World.
One small piece that stood out is the paragraph below concerning the 1974 Lausanne Congress on World Evangelisation. The meeting issued a Covenant, which was largely written by John Stott. An excellent exposition of the Covenant is in a book by Stott, and subsequently updated by Chris Wright, Christian Mission in the Modern World.
The Covenant covers 15 topics with a paragraph on each. There is much that the 2,300 leaders from 150 countries could have disagreed about. However, the most contentious sentence was the following.
