As we approach Christmas we look back at the turning point in the career of the world's most famous evangelist - Billy Graham.
He's preached the gospel to more people in live audiences than anyone else in history - more than 200 million around the world - and it all began in north London in 1954.
Claire Bowes has been speaking to the man who Mr Graham describes as the architect of international evangelism.
