True Faith and having a Crisis of Faith

[BigMrE]

So my character is a KoC wannabe (but a champion of God), but the story has presented unfolded to a point where he could/might start to question.  Now I know Sasha is agnostic, but would anyone think that this crisis could make it harder to use the True Faith powers (if at all)?  I know from a role play aspect, it's an easy answer (yes, I'm the player and he hesitates....), but what about from a mechanics point of view?

Aspect change and Compels is how I'd handle it- make one of his Aspects reflect the fact that he's beginning to question his faith, so your GM can offer a Fate point for him to hesitate at inopportune moments.
