Regarding the lecture on free will and choice

Peace, Your Honor,

I really like your lectures, they are very insightful.

I wanted to ask about what the rabbi said in the lecture on free will and choice, lesson 2.

The rabbi spoke about the combination of Luther and Calvin, that determinism is not necessarily fatalism because man has the duty to strive, and the rabbi said he did not agree with this because it is a kind of oxymoron (if I understood correctly).

What about the concept of security and effort in Judaism? Isn’t it a similar combination? Because on the one hand it is deterministic because everything is predetermined (a person’s sustenance, etc.) but on the other hand it requires effort. I suppose there is a difference but I haven’t been able to understand it yet.

Thank you very much.
