To think on that we have to get really speculative. Speculations piled on one another. What is consciousness? One could see 100 theories. But it's honest to admit we can't be sure. I believe God puts a spirit, our individual spirit, into us, and this affects our consciousness, or interacts with our consciousness, altering it. So, I think there is a separate part of us, our own spirit/soul, which has agency. Or at least, can have a real effect at certain crucial moments when other psychic forces (natural biochemical/somewhat deterministic forces) are largely canceling each other out enough (see the speculations piling up.

) So, anyways, I'm thinking (speculating), our soul/spirit has agency, and is not controlled by the body -- by passions -- unless we choose (our spirit chooses) to let it be so. Of course I don't know that much about all the characteristics of the human spirit even if I knew 10 things, right? I'd just have a sense about some things only. I feel like there are moments when we make real choices, and are not truly compelled by nature and circumstances, but have a true agency. But this is only the tip of the iceberg in some ways.
