Paul isn't going to cut it
Paul might cut it if you're Thomas Jeffson: https://en.wikipedia.org/wiki/Jefferson_Bible "Paul was the first corrupter of the doctrines of Jesus."
Not for the change of mind from "I completely don't care about humans" to "I'll make my only Son a human (to start with) and let other humans crucify him so that they could wash off the original sin".
The premises of Pascal's wager are normally presented as abstract facts about the universe - there happens to (maybe) be a god, who happens to have set up the afterlife for the suffering of unbelievers.
But, assuming we ever manage to distinguish trade from extortion, this seems a situation of classical extortion. So if god follows a timeless decision theory - and what other kind of decision theory would it follow? - the correct answer would seem to be to reject the whole deal out of hand, even if you assume god exists.
Or, in other words, respond to a god that offers you heaven, but ignore one that threatens you with hell.
