Ghostrider accepting Jesus is mentioned here (http://www.worldfamouscomics.com/tony/back20011214.shtml) in Tony Isabella's notes:
"The Challenger turns out to be Satan in disguise. Gosh, who would have seen THAT coming?
Blaze continues to struggle against the Prince of Lies, but he can't win this battle without help. Which arrives in the form of the Friend. Whose Name is now capitalized because I finally accept my obvious lack of subtlety back then.
I've never been able to turn up a copy of my original script for "Resurrection." It was probably lost in all the relocation I did back then. But my memory is pretty clear on the next scene I wrote and how I avoided using the Friend's real Name in it. Like my previous editors on the title, I believed getting too specific might be offensive to some readers.
That's not a problem here, right?
Johnny Blaze accepts Jesus Christ into his life. This gives him the strength to overcome Satan, though with more pyrotechnics than most of us can muster. He retains the Ghost Rider powers he had been given by Satan, but they are his to use as his new faith directs him."
