No, I don't think religious texts describe God as "anthropomorphic". See, for example, these verses:
The Quran, 6:103
No vision can grasp Him, but His grasp is over all vision: He is above all comprehension, yet is acquainted with all things.
'Him"? "Grasp"? "Acquainted"?
The Bible, Exodus 20:3-5
Thou shalt have no other gods before me...
for I the Lord thy God am a jealous God.
"Me"? "Jealous"?
My point is that to conceive of 'God' as a person
is anthropomorphism. Judaism, Christianity and Islam all have a fundamentally anthropomorphic conception of their deity.
Ok, mankind's description don't apply to God. But when religious people claim their texts are God's Word, then "negative theology" can't be used. In this case, it is God's own description about himself.
That's what many conventional believers in these religious traditions would likely say. But it's also something that most agnostics would be extremely skeptical about.
Those that don't know whether or not God exists wouldn't be likely to believe that a particular scripture is a self-revelation from God.
And those that don't know what descriptive meaning the word 'God' should have pretty clearly aren't accepting that scripture has already provided them with that information.
This does illustrate why the religious mystics have often been thought of as borderline-heretical by the more fundamentalist textual-literalist currents in their respective traditions. The mystics often downplay the literal meaning of their scriptures and interpret their Torahs, Bibles and Qurans in symbolic and allegorical ways.
So Pascal's Wager seems attractive for agnostics, and there is every reason for them to pray...
No, I think that Pascal's wager has almost zero attraction for contemporary agnostics.
Pascal was raised in a cultural environment in which Christianity was simply assumed. Today we live in a globalized world that resembles a religious supermarket. Right here on the internet, we have access to every religion on Earth (and on 16 alien planets). Instead of just absorbing our religion from our environment as past generations did, we are turning into religious
consumers. We pick and choose the beliefs that most appeal to us.
The problem that presents for the 'wager' is that the 'wager' assumes that there's only one legitimate religious tradition (Christianity in Pascal's thinking) and that man's only choice is to take it or leave it. But today religion's no longer a Christianity-or-nothing matter. There are countless religious options out there. Even if by chance one of them offers a true path to eternal salvation (something that most agnostics are probably strongly inclined to doubt), the chances of choosing it at random is small indeed.
And that's assuming that one could win entry into heaven by going through the religious motions in a calculated self-interested manner without any underlying belief and faith, which is doubtful in just about any religious tradition as well. (That's a problem that Pascal never seems to have recognized.)
Pascal was an interesting guy. He was a big-time mathematician and physicist who seems to have suffered some kind of psychological breakdown in midlife. He emerged from this crisis with a powerful religious passion. But he was also an intellectual of his time, fully exposed to all of the skeptical and deist currents, and he realized that he wasn't able to fully justify his newly important religious piety to his friends', or even his own, satisfaction.
So that's the context of his 'wager'. It's not so much that he was producing a novel game-theoretical argument intended to win non-believers to Christ. The 'wager' is actually a bit of rationalization on his part, intended to justify to himself and his circle of friends why his new-found religiosity, which had entirely different psychological origins, wasn't entirely irrational.
