i had a friend who talks exactly like the above post (read- memorized the same book). Then one day she did something very hurtful to me and knows im upset but never bothered apologizing. I guess she believes that it was Hashem’s doing and if i didn’t deserve it it wouldnt have happened.
always gave lots of talks about “not getting angry with the stick” but rather look at Who holds the stick. so i guess she used it the other way too. “Nothing in the world will effect a person of Bitachon, no matter what happens, cause he knows that everything Hashem does is for the good”. that means (to her) that even if she is the one who causes the bad, she owes no reparation cuz it was Gds idea and it must have been good!
Even great concepts can be bantered and misused…
