Now, there are some fairly sound theological reasons why an universal deity would choose not to routinely act as, to paraphrase Steve Jackson, a supernatural magic-battery that you can use to score free Super Bowl tickets if you roll well enough. On the other hand, miracles are by definition not subject to human rules of reasonable behavior.
On the gripping hand, apparently even the Almighty can get mildly tired of an atheist being a twerp.
PS: Yes, of course, it could have been a coincidence. Very easily. I concede this regularly, and I wouldn’t use this story to try to convert anybody, or anything, for just that reason. Still: the atheist WAS being a twerp.
