Probably 2/3 of the pop. today have never heard Billy Graham preach...and I can't prove that's why the country is going to Hell in a hand basket, but you can't prove otherwise.
I do think we were better off back then, because to some degree, the Gospel was being preached. But even Billy Graham started washing down the Gospel message and saying that infant baptism saved babies and that Hell probably wasn't hot.
If Billy Graham stood up today and preached "Repent" and that Jesus Christ was the only way to Heaven and the only way to avoid a very real Hell, he'd be run out of town.
