Yes, just as there are "deconversion" stories out there (from theism to atheism), so there are conversion stories (atheism to theism; or, as for me, from a kind of deism at best to theism). My friend Craig Keener converted from atheism to Christian theism. So did C.S. Lewis. And Peter Hitchens (Christopher Hitchens's brother). Antony Flew (following the argument from anthropic coincidences to the existence of God). Ann Rice. My friend Greg Boyd. A number of my Philosophy of Religion and Logic students over the years. And so on...
Here's a recent one - Prominent atheist blogger converts to Catholicism.
Her name is Leah Libresco. Her conversion had to do with the moral argument for God's existence. We read:
"Libresco, who had long blogged under the banner “Unequally Yoked: A geeky atheist picks fights with her Catholic boyfriend,” said that at the heart of her decision were questions of morality and how one finds a moral compass.
“I had one thing that I was most certain of, which is that morality is something we have a duty to,” Libresco told CNN in an interview this week, a small cross dangling from her neck. “And it is external from us. And when push came to shove, that is the belief I wouldn’t let go of. And that is something I can’t prove.”"
