Actually, it wasn't a "coincidence" : the guy was a professional bowler - it was skill, training, practice, and conditioning that gave him a good chance of getting the strike. Now, as for the "signing", even pros have their superstitions - instead of signing, he might have rubbed a rabbit's foot or had some kind of exotic sideways three-step hop he did for good luck; fact is, he "made" his own luck with skill. I agree with you that neither god or Yeshua helped him with the strike - to assume so, you would have to also assume that god and Yeshua had it in for the guy's opponent ,and that they didn't have any better thing to do than screw around with a bowling tournament.
