never crossed my mind that God couldn’t provide. but does He always? check out the streets of Israel. there’s your answer.
and you didn’t really answer my question about nissim. it is 100% assur to rely on a nes in order to fulfill a mitzva. (with a few exceptions like the ner tamid and isha sota – if i remember correctly) but i believe the mitzva of pirya ve’rivya does not fall under this category. and don’t tell me all these people have 100% emuna and bitachon. i won’t buy it.
