Reb Yehudah Diner Shlita, rav of beis medresh Divrei Shir, Bnei Brak, observed that when people are worried or upset, they ask למה, "Why did this occur?" or יהיה מה, "What will be?" The gematriya of למה is 75, as is are the words יהיה מה. The solution is בטחון, which is also gematriya 75.
Likutei Moharan (68) teaches, "When the yetzer hara realizes that Heaven is about to send down money to a person, the yetzer hara arranges that this person should have a reason to become angry... ָהֵמח means anger and also חומה, a wall. The anger becomes a wall, preventing the intended recipient from receiving the bounty."
The Meor Einayim (Brachos) expresses it this way: Anger is called avodah zarah, and it is forbidden to benefit (הנאה) from avodah zarah. He writes, "If a person becomes angry as he is earning his parnassah, the money that he earns from this transaction is זרה עבודה תשמישי, and it is forbidden to benefit from it, and therefore, he will lose the money so that he won't benefit from it. Therefore, overcoming anger will benefit you in this world and the next one because anger is literally Gehinom..."
This is an example of avodas Hashem becoming easier when the benefits of that mitzvah are known. It is hard to overcome anger, but knowing how much we can lose from becoming angry, that it means losing opportunities to receive money and parnassah, this will help us overcome the temptation for anger.
And even when we don't know the reasons for the mitzvos, we trust in Hashem that all the mitzvos are for our benefit, which motivates us to perform all the mitzvos.
Zera Kodesh writes that people think they must be tzaddikim to have bitachon. They know their aveiros, they feel unworthy, so they believe that bitachon doesn't apply to them. "This thought comes from the yetzer hara, but it isn't so. Hashem is kind to the good and to the bad. בטחון means טח, to paste, to connect oneself to Hashem."
Chazal (Tana d'Bei Eliyahu 22:2) write, "Everyone is obligated to say, 'When will my deeds reach the deeds of my forefathers.'" We aren't on Avraham's high level of emunah and bitachon, but we should strive to go in his ways as best as possible.
Bitachon Helps us Pass Nisyonos
The Mishnah (Avos 5:3) states, נסיונות עשרה בכלם ועמד השלום עליו אבינו אברהם נתנסה, "Avraham was tested ten times, and he passed them all."
The Bas Ayin says that Avraham passed the tests because he had bitachon. He trusted that Hashem always meant his good, and all of Hashem's mitzvos were for his benefit, so why shouldn’t he obey? When you know something is for your good, you want to do that thing. Avraham passed all his tests because he knew it was always for his benefit to do Hashem's will.
According to the Rambam (Pirush HaMishnayos, Avos 5:3), Avraham's first test was לך לך, to leave his homeland to go to Eretz Canaan. He passed this test because he believed that if Hashem sent him to Eretz Canaan, it would certainly benefit him. The Bas Ayin writes:
"It was surely difficult for Avraham to leave his birthplace and his father's home, where he was raised and was accustomed to his entire life, and go to a foreign land. He didn’t even know where he was going! But he trusted that Hashem only does kindness. His trust in Hashem gave him the strength to pass this difficult test. It states, חמש בן ואברם מחרן בצאתו שנה ושבעים, 'Avraham was 75 years old when he left Charan.' 75 is the gematriya of בטחון. The pasuk is hinting that Avraham was able to pass this test and leave Charan due to his bitachon. Because with emunah and bitachon in the Creator of all worlds that everything He does [and commands] is for the good, one has the strength to keep the mitzvos and to pass the most difficult tests."
This is implied in the words (Tehillim 37:3) טוב ועשה 'בה בטח, "Trust in Hashem, and do good." When you trust in Hashem and have bitachon, you will be able to do many good deeds.
