For a long time I was convinced my salvation lay in any man's ability to cross a street multiple times at the correct places -- places that could not be known in advance, -- and that the secrets of eternity subsisted in those decisions.
Seeking a concrete example, I imagined a prophet, either alone or accompanied by a very young -- or perhaps very old -- child. Effortlessly the prophet crossed from left to right at one point, from right to left at another. The child, sometimes scarcely mature enough to walk, sometimes supporting his aged body on a walking stick, mimicked his actions. And I saw that this secret gave back no answers. While both the child and the prophet attained salvation, it was not because of anything specific that either of them did.
To confirm this, I re-ran the same scenario without the prophet. The child matched the now invisible movements step for step, yet attained nothing.
Then I ran the scenario again, with just the prophet. He crossed in all the places he crossed before, and he did not attain salvation either.
Finally I repeated the first scenario, with both prophet and child. Once again, they crossed in all the places they crossed. Neither of them attained salvation.
