III. The Word Spreads
The news spread like wildfire. Only a few people received calls at first, but they were quick to spread the word - and friends and family were equally quick to investigate. Faithful, doubtful, or scornful, they opened their Bibles and found themselves connected Heaven's Call Center. Everyone who tried it came away convinced.
In southern California, a street preacher collapsed and had to be taken to the hospital, where he was found to be suffering from exhaustion and dehydration. His initial disappointment at finding that his tracts were nothing special had been completely overtaken by his joy in learning that the Bible in his hands could convince anyone of the existence of Jesus. By the time he collapsed, he'd been on his feet for forty-two hours - this, despite repeated Biblical warnings that he needed to stop and rest, or at least drink some water.
In Ottawa, there was a chemistry teacher - who, as an avowed atheist, had only opened his Bible to refute a particularly obnoxious commenter on his favorite message board. When his conversation with Jesus was finished, he sat in thought for a few minutes. Then he went next door, to visit his Jewish neighbors. In a matter of minutes they'd confirmed that the Torah worked just as well. Half an hour and several phone calls later, they'd discovered that the Q'uran, the Gitas, and the Book of Mormon all connected to the same unearthly voices. Within an hour of his conversion, he'd discovered that he could get the same effect on a computer or e-reader, by opening one of the sacred texts there. That, in turn, allowed him to record the conversation electronically.
And that put the story in the media. It jumped from national to international news, and for two days world events effectively ground to a halt as humanity struggled to come to grips with the effects of direct communication with the Divine.
