I am [supposed to be] learning Da'at Tevuot, The Knowing Heart, in an online course on the RaMCHal, with Rabbi Yaakov Feldman. The latest lesson is on Section 5, Chapter 3 and includes these words of wisdom having to do with the concept of free will.
.... There’s just one thing that sets humans apart from other created beings and grants us some modicum of independence, though, which is our aforementioned free will. For, as our sages put it, “everything is in the hands of Heaven except the fear of Heaven” (Berachot 33b).
That means to say that while each and everything in this world is under Gd’s direct control, our reactions to everything on the other hand (termed our “fear of Heaven” to allude to our emotional response to things) are our own and no one else's. We can react as well and wholesomely or as poorly and noxiously as we care to; that’s up to us alone.
After that, it gets more complicated :)
