Thought on Parshas Vayeshev:
Yosef holds sinners liable, as he establishes that human nature is indeed stronger than his baser inclination.
The question is that Yosef experienced the apperation of his father who showed him the potential he has of being on the efod. How can this possibly apply to other people.
The answer is that every person has the ability to be a unique being, unlike anyone who ever lived. In his/her specific area, all people have the ability, if they live their life correctly (which few do), to be truly unique.
In the context of one- of – a – kind there is no difference between Yosef’s potential, or anyone else’s potential. They are both priceless (something that has no parallel has no limit on its value).
This is enough to encourage all of mankind to overcome their smallness, precisely the way it did for Yosef.
