The Torah enjoins us to keep it’s laws, and good will come of it:
אִם בְּחֻקֹּתַי תֵּלֵכוּ וְאֶת מִצְוֹתַי תִּשְׁמְרוּ וַעֲשִׂיתֶם אֹתָם – If you follow My statutes and observe My commandments and perform them… (26:3)
It is curious that the Torah predicts that good outcomes follow good actions, given that we are not meant to act for personal gain when performing mitzvos.
Rav Shach explains that it is not a reward, so much as it is a reality. הליכות עולם לו – the ways of the world are Hashem’s (Chabakuk 3:6). We say this when we say korbanos at the end of davening, and we quote the ma’amar Chazal that expounds אל תקרי הליכות אלא הלכות – Read it not as ways, but as laws. The הלכות, the Torah, that we bring in to the world, dictates the הליכות, the ways, of Hashem’s world.
Our actions are significant, and have a very real effect on the world – the extent to which we push ourselves influences how Hashem’s instructions trickle, filter, and amplify, ultimately developing into אִם בְּחֻקֹּתַי תֵּלֵכוּ; that וְנָתַתִּי גִשְׁמֵיכֶם בְּעִתָּם, that וְחֶרֶב לֹא תַעֲבֹר. In this way, our actions affect our outcomes.
The Torah instructs us with verbs – תֵּלֵכוּ – we must follow the path, and then וַעֲשִׂיתֶם אֹתָם. Judaism cannot be carried out passively.
The Alter of Slabokda would lament that people lack clarity and belief in this. He said that in the same way that people are certain that crop growth results from rain, they should be equally certain that rain is sent when society is dignified and kind. וְנָתְנָה הָאָרֶץ יְבוּלָהּ results from וְנָתַתִּי גִשְׁמֵיכֶם בְּעִתָּם, as much as וְנָתַתִּי גִשְׁמֵיכֶם בְּעִתָּם is a result of אִם בְּחֻקֹּתַי תֵּלֵכוּ.
We are in the driving seat – הליכות עולם לו.
The Chafetz Chaim would scold his students when they requested his blessing. We should be have enough faith that if we do the right thing with enough frequency, good will ultimately come of it.
If we are not performing our duties as Jews to the best of our abilities, do we have the right to complain? By taking care to speak to everyone gently and politely, is there any doubt that everyone you come in contact with will be politer and gentler for it? That’s how you begin to change the world.
