  Regarding the larger question of obeisance to God, Saadya (in chapter 3 of the Amânât) provides what he takes to be a reason-based account of why one ought to follow God and obey His laws, and can in this way be seen as providing a reason-based appraisal of revelation most broadly construed. This argument is provided in 4 parts, and centers, in turn, on the reasonableness of God's expecting us to render thanks to Him, the reasonableness of God expecting us to respect Him and His name, the reasonableness of God's expecting us to act rightly towards fellow humans, and the reasonableness of God's giving us commands and prohibitions for the express purpose of being able to give us rewards. In this discussion, Saadya in yet another way employs reason in support of revelation.  Here, revelation is once again helped — at least in the sense of supported — by reason.
