If people are quantitatively less likely to do business with people who emit heresy-signals (even subtle ones, like being insufficiently enthusiastic while praising God), then believing in God really _is_ a good financial decision, which is a _successful prediction_ that legitimately supports the "Divine Providence financially rewards the faithful" hypothesis. With sufficient mental discipline, the occasional freethinker might be able to entertain alternative hypotheses ("Well, maybe Divine Providence isn't _really_ financially rewarding believers, and it just looks that way because of these-and-such social incentive gradients"), but given the empirical adequacy of the orthodox view, it would take a level of sheer stubborn contrarianism that isn't particularly going to correlate with being a careful thinker.
