Everyone uses selective reasoning. Without it, we'd just have to accept everything anyone told us ever. For example, I wouldn't believe you if you told me you have a pet mongoose called Alan who plays tennis at weekends. Because I've decided it's unlikely and that I will only believe things where I have evidence for them. I would believe you if you told me the sky is blue, because it tallies with my own experience.
The only difference between this and a viewpoint on god(s) is what criteria have been selected. You wont believe a 2000 year old story but you will believe a scientific paper. You've just set different standards, not necessarily correct or better ones.
If God exists and judges us on our choices, what's the point in living if He'll interfere with our choices?
Personally, I think he's incredibly lucky or has a really quick thinking guardian angel. But as BM says, who cares what saved him, the important thing is that he's still alive and, in this case, even if he claims it was Alan the mongoose, I'm not going to complain
