More than a thousand recordings from evangelist Billy Graham's ministry have been made available online for the first time.

Many of the sermons date back 60 years, including Graham's famous evangelistic crusades and his remarks at President Lyndon Johnson's funeral.

The Billy Graham Audio Archives can be searched by location, date, and topic.

Topics range from divorce to Christians' relationship with the world.

The files are being released as America's most popular evangelist prepares to celebrate his 93rd birthday.

The Cincinnati Post reports that Graham has preached the gospel to more people than anyone in history.
