There Is No Trait as Great as Bitachon
There is no trait as great as bitachon, as it says, “Blessed is the man who trusts in Him,” for such a person believes that the world has a G-d Who is all-capable and Who oversees everything that happens, as it says, “Blessed is the man who trusts in Hashem, for whom Hashem is his source of trust.” He is guaranteed that he will not lack his needs, as it says, “Place your load onto Hashem, and He will provide for you.” And this is on condition that he is genuinely trusting in Hashem with all his heart and without any doubts. Moreover, since he trusts in Hashem, he will occupy himself with Torah and mitzvos without any other thoughts at all.
(Shaarei Kedushah Unit 2 ch. 4)
He Who Trusts in Hashem Is Blessed in This World and in the Next
...As Rabi Yehuda Hanassi asked: Why does it say, “Trust in Hashem forever and ever, for Hashem created the worlds with [the Name] Kah”? (Yeshayahu, 26:4). This is because if someone places his trust in Hakadosh Baruch Hu, then Hashem is a shield for him in this world and in the World to Come. Because they trusted in Hashem forever and ever, they had a shield in both worlds.
(Menachos 29b)
Even if He Has Bad Mazal, Bitachon will Bring Him Blessing
Even though sometimes a person is not worthy of anything good, but rather his mazal is bad, he should still trust in Hashem yisbarach. When it says, “Trust in Hashem forever and ever, for Hashem created the worlds with [the Name] Kah,” it means that Hashem created this world and the Next World with His Name Kah, and therefore one should trust in Hashem forever that He provides his needs from the Upper World, and all is good. Even if a person has bad mazal in this world, his trust in Hashem reaches all the way to the Upper World, the World to Come. Thus, Hashem safeguards him in this world and in the World to Come, for Hashem provides the baal habitachon complete protection.
(Maharal of Prague, Nesivos Olam Vol. II, Nesiv Bitachon ch. 1)
The Power of Bitachon Is Imbedded in Man’s Nature
There are people who believe that the middah of bitachon belongs to exalted men of bygone days; but these people are mistaken. Hakadosh Baruch Hu imbedded the middah of bitachon into the very nature of man. It is an inherited trait.
It is a fact that people tend to believe someone who promises them something, even if they see that he ultimately fails to follow through and he disappoints them, or that he is unable to make good on his promise. Often a person is sure of himself and believes in his own strengths and does not despair even in times of difficulty. Clearly this power of bitachon exists within the nature of a person and it is not impossible for any person to use this middah in the right and proper way.
Therefore, Chazal used the expression “anyone who applies his trust to Hashem.” This power of bitachon is part and parcel of human nature, and one need only “apply this” to Hakadosh Baruch Hu and to trust in Hashem, using this power properly as Hashem intended for it to be used, and not using it in an improper way, such as by placing one’s trust in other people.
