Trusting God even when we can't or don't want to because nothing makes sense--especially then--is freedom, freedom from the pressure of needing to be certain when certainty has left us. Choosing to trust the Creator then and there isn't irrational, but a humble admission that our rational faculties are limited for grasping the eternal and infinite. To call such trust irrational has already put on a pedestal the rationalistic pattern of faith that deeper faith calls us to transcend.
