A friend of mine shared a beautiful insight with me:
there's no such thing as a possibility of 50%. There're only two percentages that exist. Everything in life is either 0% or 100%. Either HaShem wants it for you - or He doesn't! Something can scale at 0% today but be 100% tomorrow. And vice versa. That is to show us that we're fully dependent on HaShem, and He controls the world.
This Shabbat is b"H "Shabbat Shira" -- the "shira" reference is from this week's Parsha; in Parshat Beshalach, Bnei Yisrael sang "Az Yashir" to thank G-d for the miracle of kriyat yam suf (splitting of the reed sea). Chazal teach us that making matches/dating/finding your spouse is likened to kriyat yam suf. It's just as arduous to find that right guy (or gal) --as it is to split the sea.
How on earth is that possible? Afterall, NOTHING is difficult for HaShem. He doesn't "sweat"! He's All Mighty. He's all powerful. He's the Master-Of-The-Universe. The splitting of the sea isn't any more difficult for HaShem than creating a wind breeze for a second.
So how can shidduchim be difficult for Him???
The answer is that shidduchim ARE easy for HaShem to make; Chazal are not referring to HaShem's actual matching and formation of shidduchim. Rather, they're referring to emunah! Just like it was difficult for Bnei Yisrael to keep up their emunah in HaShem when they were faced with tons of Egyptian soldiers and had nowhere to run, so too it is difficult to have emunah in HaShem when one is looking for his or her spouse.
When faced with adversity, people can begin to have misconceptions about the solution. For example: I'll only find my zivug when I meet this well-known-shadchan-who-made-100-matches, when I lose x amount of weight, when I have a higher paying job, etc. That mentality is flawed. That person is placing his emunah in the shadchan and his own power...not HaShem's power! We need to know that although we must do our hishtadlut, ultimately, it is HaShem who sends us our zivugim! It's either 100% or 0%; either He thinks it's the right time for us, or He doesn't.
Around a year ago, I attended a wonderful shiur about this parasha that really made a difference in my life. The Rabbi explained that hope is the essence of a successful person. Before the splitting of the sea, many members of Bnei Yisrael panicked -- "what will happen to us??! Will the Egyptians all murder us now?!"
But Nachson ben Aminadav didn't panic; he jumped into the (unsplit) ocean. After he jumped in, the sea split!
His action prompted the miracle because he trusted in HaShem; he KNEW HaShem is helping and will help them. The truly successful individual is the one who knows where his success comes from. If you have hope and emunah in HaShem, you're set. You will do well in school. You will get married. You will have children. You will have a parnassah. Just (as the Journey song preaches) -- "don't stop believing!"
HaShem loves us and is taking care of us, so don't give up! Keep trying with your full 100%.
It's a segulah (especially for finding your zivug) to recite "Az Yashir" in Shul this Shabbat -- Shabbat Shira -- with extra kavana! B"H all of our tefillot should be answered l'tova.
Shabbat shalom :)
