Trust According to One's Level
Emunah & bitachon
In the section on bitachon in HaMaspik L'Ovdei Hashem, Rav Avrohom teaches that the degree of trust a person must have depends on his spiritual level and his closeness to Hashem. He gives practical examples of how this trust should shape the actions of a true believer.
