In the Guidance move the Priest is ultimately interrogating "their heart" for advice.
So either the Player expresses what they believe/imagine that the Priest's heart says...
Or the World will tell the Player what they believe/imagine that the Priest's heart says...
Or there will be silence...
It's not about perception and the parsing of factual information. It's not about effectiveness :P
It's about self reflection and dramatic choices. The actual info is irrelevant, as it will always offer Advantage no matter what. We are interested in having the Priest question their heart. Or to see how the Priest reacts to the way someone else (the World) imagines the Priest's heart to be. Also keeping in mind that the World was just now informed of what the Priest is afraid of in this situation, and knows what their Issue and Doubt are. So most probably the World will do something to facilitate and enhance the DRAMA of the Priest's story... which is their whole job anyway :P
Does this clarify?
