If one’s income and one’s health and everything
else has already been decided, how can one hoe hope to change things through daily prayer?

The rabbis explain although we are taught, ein Mazal LeYisrael, there in fact is mazal and it’s difficult for an individual person to change their Mazal, so again what are we hoping for? 

This week our forefather Isaac gives us a lesson in rising above or tunneling through and changing what was predicted to be to what can be.
