My dear brothers and sisters, warriors of Hashem:
The holy Tzaddik R' Tzadok HaKohen of Lublin writes (Tzidkas Hatzadik 154):
"Just as one must believe in Hashem, so too, one must believe in themselves!"
R' Tzadok goes on to say that Hashem cares so much about YOU thathe is "busy" with YOU. What YOU do makes a difference to Hashem in a BIG way. Hashem derives pleasure (K'Vyachol) from YOU when you do ratzon Hashem!
It says in this week's Parsha (Parshas Yisro 19:9) Hashem said to Moshe that after Kabalas HaTorah, the Jews will "Believe in you [Moshe] too", and it says in last week's Parsha (B'Shalach 14:31) that the Jews feared Hashem and believed in Hashem and in Moshe, the servant of Hashem.
R' Tzadok explains that Moshe was the embodiment of the entire Klal Yisroel; There was a little piece of every Jew's Neshama in Moshe's exalted Neshama. Therefore, what the Torah is telling us is that each and every Jew must believe in Moshe i.e. each Jew must believe in themselves!
The Yetzer Hara wants us to think bad about ourselves. The Yetzer Hara wants us to think of ourselves as small and incapable people. The Yetzer hara wants us to be depressed and unforgiving of our past. the Yetzer Hara doesnt want us to believe in ourselves!
That is NOT what Hashem wants! Hashem wants us to BELIEVE in our strengths, our capabilities, our ability to overcome evil and achieve greatness,
Each and every one of us, no matter how far we have fallen, CAN ACHIEVE GREATNESS!
Each and every one of us, no matter how deep we have sinned, CAN BE AS RIGHTEOUS AS MOSHE RABBEINU!
Each and every one of us has a piece of G-d in our Neshama!
We all believe in Hashem! We must all start believeing in ourselves!
We can all be great, not despite our past failings, but BECAUSE of our past failings!
"Shiva Yipol Tzaddik V'Kam- A Tzaddik falls seven times and gets up" The greatness is not despite the 7 falls, it is a result of the 7 falls!
WE ARE ALL LITTLE MOSHE RABBEINUS! BELIEVE! BELIEVE! BELIEVE!
Chazak V'Ematz!
