Constant Hashgachah
One who relies on and trusts in Hashem’s Name is safeguarded from all evil and harm, for hashgachah constantly watches over him, as it says, “Behold Hashem’s Eye is upon those who fear Him and on those who hope for His kindness....” When a person leaves all his affairs in the Hands of Hashem and casts off their burden, it turns out that his nefesh will be constantly attached to Hashem yisbarach, and Hashem will then be close to him and will oversee all that he does, and all his needs will be taken care of by Hashem.
(Based on Toras Haminchah by Rav Yaakov Skoli, a talmid of the Rashba, ch. 14)
The Blessing of Bitachon
For he who trusts in Hashem and does not rely on the things that I mentioned [i.e., wisdom, strength, wealth, and relatives], not only will Hashem do his will and bless him, but he is also granted these four things that I mentioned. How so? If he is not wise, Hashem gives him wisdom ... if he is not strong, Hashem holds his hand and strengthens his heart ... if he is not wealthy, Hashem makes him wealthy ... and if he is in a foreign land, separated from his relatives, Hashem brings him close....
(Based on Menoras Hama’or, Rav Yisrael Ankeva, ch. 14)
Blessing, from the House of Hashem
When a man strengthens his middah of bitachon, then certainly blessing will come into his home ... and therefore, now, when there are many difficulties facing us in the world, and we have almost no source of parnassah in the natural order of the world, we need to place our trust in Hashem, knowing that nothing is difficult for Him. Certainly, through our trusting in Him, He will send His blessing to us from His House ... and this is hinted to in the words of the navi (Tzefanyah 3:12), “Those who will remain in your midst will be an oppressed and impoverished nation, but they will rely on the Name of Hashem.” The navi does not explain there what will be the result of trusting in Hashem’s Name, but in another place it explains: Blessed is he who comes with the Name of Hashem, we bless you from the House of Hashem, the Source of all blessings and shefa.
