Mr. Graham was by no means unique in American history as a popular evangelist. George Whitefield in the mid-18th century, Charles G. Finney and Dwight L. Moody in the 19th century, and Billy Sunday at the turn of the 20th were all capable of drawing vast crowds.

But none of them combined the ambition, the talent for organization and the reach of Mr. Graham, who had the advantages of jet travel and electronic media to convey his message. In 2007, the Billy Graham Evangelistic Association estimated that he had preached the Gospel to more than 215 million people in more than 185 countries and territories since beginning his crusades in October 1947 in Grand Rapids, Mich. He reached hundreds of millions more on television, through video and in film.

“This is not mass evangelism,” Mr. Graham liked to say, “but personal evangelism on a mass scale.”

Ball-Playing Dreams

William Franklin Graham Jr. — Billy Frank to his family and friends as a boy — was born near Charlotte on Nov. 7, 1918, the first of four children of William Franklin Graham and Morrow Coffey Graham. He was descended on both sides from pre-Revolution Scottish settlers, and both his grandfathers were Confederate soldiers.

Though the Grahams were Reformed Presbyterians, and though his father insisted on daily readings of the Bible, Billy Frank was an unenthusiastic Christian. He was more interested in reading history, playing baseball and dreaming of becoming a professional ballplayer. His worldliness, his father thought, was mischievous and devilish.

It was the Rev. Mordecai Ham, an itinerant preacher from Kentucky, who was credited with “saving” Billy Graham, in the autumn of 1934, when Billy was 16. After attending Mr. Ham’s revival sessions on a Charlotte street corner several nights in a row, Billy walked up to Mr. Ham to make a “decision for Christ.”

“I can’t say that I felt anything spectacular,” Mr. Graham recalled years later. “I felt very little emotion. I shed no tears. In fact, when I saw others had tears in their eyes, I felt like a hypocrite, and this disturbed me a little. I’m sure I had a tremendous sense of conviction: The Lord did speak to me about certain things in my life, I’m certain of that. But I can’t remember what they were.”

Returning home with a friend that night, Mr. Graham said, he thought: “Now I’ve gotten saved. Now whatever I do can’t unsave me. Even if I killed somebody, I can’t ever be unsaved now.”
