America's most famous preacher is 93 years old.

The Rev. Billy Graham of North Carolina is marking his birthday Monday amid a new flurry of activity. Within the last month, his 30th book, "Nearing Home," was published, and nearly 1,700 audio files from his public ministry have been posted online.

Graham served as an adviser to presidents and toured the world for his famous crusades. He says he tries to spend as much time with his family and occasionally meets with Christian leaders and old friends. He also keeps up daily Bible reading and prayer time, and has said he hopes to preach a sermon one last time.

Graham's public career spanned more than six decades. He first rose to national prominence during a 1949 revival in Los Angeles.
