  God gives His followers more opportunity to reap rewards by making even the self-evident norms of moral living matters of divine obeisance.  We might say that for Saadya, God supplements a natural law ethics (and/or a Virtue Theory ethics) with a divine command theory for the purpose of increasing human rewards. reason, in this way, is helped by revelation. And yet again, in the very composition of an account of the reasonableness of revelation, Saadya here too shows revelation to be helped — at least in the sense of supported — by reason.
