You asked —
“Why would G-d care what I eat or light or say?”
It’s a fair question, and notice the picture hiding inside it: a G-d far away in heaven, oddly micromanaging groceries. If that were the picture, the rules would be absurd. It isn’t the picture.
You met the real one on the Path: G-d wanted a dwelling in the lowest world — in physical, ordinary, Tuesday-afternoon life. Not despite its ordinariness. Because of it. Which flips your question inside out: the physical details aren’t beneath G-d’s interest. They’re the address G-d chose.
So a mitzvah involving food or candles or words isn’t a regulation — it’s a meeting place. The blessing before coffee doesn’t change the coffee; it changes the moment into an appointment. The candle Friday evening is physics plus fire plus wax — and a weekly rendezvous three thousand years running. Judaism is so physical on purpose: a religion of pure thoughts would leave your actual life — hands, kitchen, doorpost, dinner — out of the relationship. Yours wants all of it in.
There’s a Chassidic way of saying this that’s worth keeping: other traditions climb away from the world to find holiness. Judaism pulls holiness down into the world — through exactly the small physical acts you’re asking about. Every “why would G-d care about that?” has the same answer: because that is where you live. And you’re the one being met.
