Excellent question, kids. The Sefas Emes [Vayikra, 5631] teaches a fundamental lesson based on a verse in Tehillim* and its Midrashic explanation. We can actually be messengers of HaShem in every action that we do! The Midrash explains that the word מַלְאָכָיו [His messengers] in the verse* is referring to Bnei Yisroel. Therefore, before a person begins doing something, he needs to prepare himself with the following thought: “My only intention in doing this is to fulfill my mission that HaShem is sending me on.” With such preparation, teaches the Sefas Emes, a person will know what is good in HaShem’s eyes.
*בָרְ כוּ ה' מַלְאָכָיו גִּבֹּרֵי כֹּחַ עֹּשֵי דְבָרוֹ לִּשְמֹּעַ בְקוֹל דְבָרוֹ -- תהילים קג:כ
Zeidy – after Pesach, we are even more enthusiastic about being Avdei HaShem. How can a person always know that what he is doing is good in HaShem’s eyes?
