My Grandmother was a great fan of both Billy Graham and Bishop Sheen; and I grew up listening to both of their sermons and talks on the television machine.
Graham accomplished great things while remaining a humble man - as did Sheen.
I had heard of him before but hadn't read or seen any of his sermons. I ended up spending the next good while watching Bishop Sheen clips.
Wildly undenominational that I am, Sheen came across as a true preacher of the Gospel, as Graham was.
It was a pretty neat discovery.
