From the following Passuk in Parshas hamon and Rashi thereon we see how a Yid must trust that Hashem has many different avenues for how to provide:Shemos 16:32
וַיֹּ֣אמֶר מֹשֶׁ֗ה זֶ֤ה הַדָּבָר֙ אֲשֶׁ֣ר צִוָּ֣ה יְהֹוָ֔ה מְלֹ֤א הָעֹ֙מֶר֙ מִמֶּ֔נּוּ לְמִשְׁמֶ֖רֶת לְדֹרֹתֵיכֶ֑ם לְמַ֣עַן ׀ יִרְא֣וּ אֶת־הַלֶּ֗חֶם אֲשֶׁ֨ר הֶאֱכַ֤לְתִּי אֶתְכֶם֙ בַּמִּדְבָּ֔ר בְּהוֹצִיאִ֥י אֶתְכֶ֖ם מֵאֶ֥רֶץ מִצְרָֽיִם׃
Rashi
לדרתיכם. בִּימֵי יִרְמְיָהוּ; כְּשֶׁהָיָה יִרְמְיָהוּ מוֹכִיחָם לָמָּה אֵין אַתֶּם עוֹסְקִים בַּתּוֹרָה? וְהֵם אוֹמְרִים נַנִּיחַ מְלַאכְתֵּנוּ וְנַעֲסֹק בַּתּוֹרָה, מֵהֵיכָן נִתְפַּרְנֵס? הוֹצִיא לָהֶם צִנְצֶנֶת הַמָּן אָמַר לָהֶם אַתֶּם רְאוּ דְּבַר ה', שִׁמְעוּ לֹא נֶאֱמַר אֶלָּא רְאוּ, בָּזֶה נִתְפַּרְנְסוּ אֲבוֹתֵיכֶם, הַרְבֵּה שְׁלוּחִין יֵשׁ לוֹ לַמָּקוֹם לְהָכִין מָזוֹן לִירֵאָיו
The abovementioned point, that Hashem can use even “farfetched’ avenues to provide is highlighted in the following story brought in the Gemara: A certain person came before Rava to request charity. He said to him: On what do you normally dine? He said to him: On a fattened hen and aged wine. He said to him: And were you not concerned for causing a burden to the community by expecting such opulent foods? He said to him: Is that to say that it is from their funds that I eat? I eat from the support of the Merciful One. This would seem to be a reasonable argument, as we already learned that in the verse “the eyes of all wait for You, and You give them their food in its time” (Psalms 145:15), the phrase: At their time, is not stated, rather “in its time.” This teaches that the Holy One, Blessed be He, gives each and every one his personally appropriate sustenance at its proper time, and the community is merely His agent in discharging His will. Therefore, the man is justified in maintaining his standard.In the meantime, while they were talking, Rava’s sister, who had not seen him for thirteen years, came. And as a gift, she brought him a fattened hen and aged wine. Rava said to himself: What is this that happened in front of me that suddenly I am brought food that I do not usually eat? He then understood that this was a providential response to what he had earlier said to the man. Rava said to him: I have responded [na’aneti] to your contention. Arise and eat.
