Question: In the articles of Kabbalists it is written that there is complete and partial faith. What is the difference between them?

Answer: You do not know what will be revealed to you at the next level, but what has now been revealed in all your Kelim, when they are all filled with the light of Hassadim it means that you are in complete faith.

Partial faith manifests itself when not all of your Kelim are filled with Ohr Hassadim.
