“The one who has faith and trust in Hashem is the one who knows wholeheartedly that everything is conducted by Hashem’s hand and, consequently, everything is for his very best at every moment.  He knows that he is in the Creator’s hands always.  He does not know that things will work out the way he would like them to, but he trusts Hashem that whatever He does and will do is the best thing for him and this calms him.”  ~ Chovos Halvovos
