If I sent the same emails to Dan but it was about a Catholic that missed the flight because of his religious beliefs do you think it would have been posted to the main site?
Thousands of Dan's readers don't desecrate the Shabbos. He posted a story of someone who didn't desecrate the Shabbos (which is an obligation only for Jews) and his life was saved.
Does this prove there's a G-d? No.
Does this prove that the Jewish way is correct? No.
It's just a beautiful story for the thousands of readers who love the Shabbos, and believe that the Shabbos protects us.
There is a song that Jews sing on Shabbos, that says "If I keep/guard the shabbos, G-d will guard me".
