In such a case a person is called a sinner. He cannot justify the Creator with regard to what he feels in the world, and to this extent the Creator is concealed from him.
If we feel bad, we do not feel that this bad feeling stems from the Creator. It is the special intention of His bestowal unto us.
If the feeling is good, we feel that it stems from the Creator, but if the feeling is bad, if we have not prepared ourselves to feel negative impacts as positive, we do not feel that they stem from the Creator and instead feel them as torments.
