Ya know, I never really thought about Pulp Fiction in this light but...

You could read Jackson's character's obsession with that quote as faith sans interaction with the source material. He never read the bible, he just found something cool and started saying that and it turned into something approaching genuine belief over the course of the movie.

When Pete says it it's the exact opposite. It's an appeal to pulp spiritually similarly lacking in engagement with the source materal except here it doesn't result in anything. In pulp fiction Jackson's character starts off with a lie then stumbles into true faith. Pete starts with a lie upon a lie and faith never even enters into the equation. It's just preformative all the way through.

Thanks for coming to my TED talk.
