Brachos for Remaining Faithful to Hashem:
The Medrash (Shemos Rabbah 51:1) states: “’These are the numbers of the Mishkan.’ Rebbe Tanchuma bar Abba would start: ‘A trustworthy man will have many blessings, but he who hastens to become rich will not go unpunished (Mishlei 28:20).’ ‘A trustworthy man will have many blessings’ – we find that Hashem brings blessings through the hands of anyone who is trustworthy. But if someone is not trustworthy – ‘he who hastens to become rich will not go unpunished’.”
The Sefas Emes explains how a trustworthy man brings blessings to the world by saying that Hashem’s essence is goodness and He desires to send all sorts of good things and Heavenly influences to every person. However, if a person is not trustworthy, he may misuse the good things that Hashem gives him. If such a person is given money or honor, he may fail to remember that Hashem is the One who gave him all that he owns, and he may use what he has for bad purposes and sin.
Hashem is the ultimate truth. He only wants His influences to be used for truly good purposes, and certainly not for sin. If He sees that people are untrustworthy, He will withhold His goodness so that it is not used for bad. But if Klal Yisroel is trustworthy and properly uses the goodness that Hashem sends, they are worthy of receiving all His blessings.
The Medrash is saying that when Klal Yisroel is trustworthy and can be relied upon by Hashem to make good use of His kindness, they bring blessings to the world and are able to receive Hashem’s great influences.
We similarly find regarding Shabbos that it is stated (Bereishis 2:3): “And Hashem blessed the seventh day.” Shabbos is a day of blessing because the entire world returns to its original state wherein Hashem sends His blessings and holy influences to those who act properly.
