Commitment to a god and belief in that god are separable mental states.

Evidence

Commitment implies belief, but one could believe in the existence of a god without being committed to that god. In the Abrahamic tradition, belief and commitment are conflated, but that is just an odd consequence of monotheism, which, despite its spectacular cultural success in the last two millennia, was historically a rarity in the cultures of the world. … These observations led to two insights: (1) that commitment to a god does not imply denial of the existence of other gods (except in the peculiar Abrahamic tradition), and (2) that one can believe in the existence of a god without worshipping this god. — Norenzayan, Ara, Big gods - how religion transformed…, 373
