TBT: The Anaf Yosef on Medrash discussed the hashkafic issues here, second answer.
it is obligatory to rely on Divine intervention.
nevertheless one is obligated in hishtadlus.
Interesting way of putting it. I would say Hashem gives us the ability to do Hishtadlus, and only with Hashem’s help will it work. However, if possible, one may not “rely” on Hashem coming to his aid, but must trust that if it comes to that, Hashem will help (also see Anaf Yosef)(what you said is vauge. If that is not what you meant, please clarify)
