Interesting at first...
At first it seemed like a very personal story, but then it degraded into a religious message, and by combining these two, you basically imply that everyone that doesn't believe in god, is this person we saw in the flash.
Instead of telling us what god means for you, you tell everyone how bad it is without god. Now I personally don't believe in a god, because I believe the real truth has to be something way more complex, and not a god some people thought up to feel a sense of structure in their lives and dominate others by telling them they don't worship it enough.
So all I can say about this flash is, keep it to objective, and don't combine a call to action with a personal story, just so you can get your religious message across, because to me it has the same value as a subliminal coca-cola message in a good motion picture.
