From the passage you posted, the sentence expressing certainty is 'This dark assertion will be illuminated later on'. We use 'will' when we believe that a future state is certain to occur.

However, it states a possibility, not a certainty.</span>
Baring is a verb. Specifically, it is the present participle of the verb to bare, which means to uncover or expose. Someone who bares his soul to another person, for instance, is exposing his true thoughts or feelings in a vulnerable manner.
