Think4- yes, of course we should be happy with our lot and be serving Hashem – but to say that “I am happy being single” is like saying “i am happy having a nisayon” – we don’t ask for nisyonos even though they are good for us and we should say, “I am happy to be where I am and I hope to be able to serve Hashem even better.”
We are having the same conversation Elkanah and Chana had in Sefer Shmuel. Elkanah said to Chana, “Aren’t you happy with what you have, am I not better to you than ten sons?” Because yes, even without children Chana could serve Hashem. This is like you saying, “What’s wrong with being happy with being single, or childless ch”v?”
Chana didn’t answer him but davened to Hashem, saying, “Hashem please let me use everything, every part of my body, to serve Hashem. Please give me a son, a regular child who will serve You, Hashem.” And we see that her Tefilos were answered.
Similarly, I think it is right for a single girl to daven to Hashem, saying, “Hashem please let me use everything You created me for, please let me marry a husband with whom I can build a Bayis Neeman B’Yisrael to glorify You.” And may every one of our tefilos be answered for the good.
Say “I am happy serving Hashem now, and I hope to serve Hashem more with the added responsibility of marriage.” But to say “I am happy being single” strikes me the wrong way.
SJS: Absolutely!! Of course a person can, should, and MUST develop themselves to serve Hashem before they get married. Yes marriage brings with it responsibilities and makes it hard to do certain things that used to be taken for granted, but that is part of the challenges that makes marriage the tremendous vehicle of serving Hashem that it can be. Marriage does not make it harder to serve Hashem, it makes it easier.
