Billy Graham, had a perfect speaking skill. He just found religion and off he went! He really had a simply message, delivered with a convincing open style. I am convinced that most of his appeal was his delivery! Even i, am impressed when he is speaking at the pulpit...and nearly wishing he had something for me! He kept his message simple and to my knowledge never envolved himself in some scandalous affair or situation. I heard on the news that he was worth 9 million dollars...not a lot compared to other televangelist. I also heard that it is suspected that his son Franklin wrote his last books. In my mind, he is just one of those 'decent people'...that could be from any religion.

He was promoted by publishers Randolph Hearst and Henry Luce: Born on a prosperous dairy farm and educated at Wheaton College, Graham first gained national attention in 1949 when the publishing magnate William Randolph Hearst, searching for a spiritual icon to spread his anti-communist sentiments, discovered the young preacher holding forth at a Los Angeles tent meeting. Hearst wired his editors across the nation, “puff Graham,” and he was an instant sensation.

Hearst next contacted his friend and fellow publisher Henry Luce. Their Wall Street ally, Bernard Baruch, arranged a meeting between Luce and Graham while the preacher was staying with the segregationist Governor Strom Thurmond in the official mansion in Columbia, S.Car. Luce concurred with Hearst about Graham’s marketability and Time and Life were enlisted in the job of selling the soap of salvation to the world. Time, alone, has run more than 600 stories about Graham.

Once I found out that Billy Graham was peddling the idea of chasing down a Jewish zombie and asking him to forgive you for something done by two naked people who chatted up a serpent in a magic garden, I couldn't stop thinking of him as a complete buffoon. The only thing that's changed is his status as the late Reverend William Buffoon.

This might be a little helpful. It doesn't reveal much, but it gives a general idea.
Just another christian charlatan.

Just like any other sales pitch, it is all about building excitement in the product and engaging the customer. convince them that they NEED what you're selling, and the product sells itself. It is brainwashing and subtle hypnosis and so many other persuasive arts all rolled up into one.

Never been affected by preaching... even when Oral Roberts visited Puerto Rico. Didn't worked on me.

LOL!
His converts are likely a good part of the 85% white evangelicals who voted for Trump and champion the NRA. I've never seen anyone change for the better after "conversion" except maybe for certain Haitians, who gladly exchanged Christianity for voodoo, since it allowed them to prosper.

The Haitians even read the Creole New Testaments for themselves, and many took it literally-raising the dead, seeing people healed from deadly diseases, seeing miracles.
The missionaries, of course, went to doctors because they could, and didn't do miracles.

I don't think "god" had anything to do with the miracles, but the people sure did. Jesus himself said that "ye are gods" and told people that if they told a mountain to fall into the sea, it would obey them, never mentioning that it should be "god's will" or stipulating a pious act. In fact, the Greek word translated "whosoever" includes all declensions, thus including non-humans in that promise.
