  Following upon this delicate interplay of reason and revelation, it is interesting to note how the proofs for creation come up again in Saadya's treatment of resurrection. While the reasons Saadya gives for believing in the truth of resurrection have primarily to do with the reliability of Tradition, Saadya additionally invokes his reason-based proofs of creation ex nihilo to support the at least prima facie reasonabless of such beliefs. Speaking against the critic who finds the very idea of God's rejuvenating the dead philosophically untenable, Saadya stresses that resurrection is not “rejected by reason because the second creation of a thing which was already in existence and became dissolved, is more acceptable to reason than the creation ex nihilo” (158). Since the idea of something's being created ex nihilo is less reasonable than the idea of its being re-created, and since the idea of creation ex nihilo has already been proven true by reason, therefore, a fortiori, surely belief in resurrection is at least reasonable. Here, Saadya's proof for creation ex nihilo emerges in the service of his belief in resurrection.
