Rabbi Yosef Caro published the Shulchan Aruch, the Code of Jewish Law. This concise codification of all Jewish law which is germane today was an extension of his Beit Yosef commentary (see entry for the 11th of Elul).
The Shulchan Aruch is divided in to four sections: Orach Chaim details the laws pertaining to daily life, lifecycle events, and holidays. Yoreh De'ah. laws which a practicing rabbi must be proficient in, such as complex nuances of the kosher laws, laws of mikvah, and laws of slaughtering. Even Ha'ezer, laws of marriage, divorce, reproduction, and the like. Choshen Mishpat, monetary and judicial laws; required study for a member of a rabbinical court.
To this very day, the Shulchan Aruch serves as the primary halachic guide for Jewish life.

Rabbi Yosef Caro- The Master
Pessimism comes with a thousand arguments. Maybe you don’t deserve to be saved from the mess you’ve gotten into. Maybe you deserve punishment, G‑d forbid. Maybe the only way to save your soul is through a dark tunnel.
That’s not called trust. Trust means you have not a shade of doubt that He will deliver—no matter who you are and what you’ve been up to—and it will all be good, every step along the way.
As for your mess-ups, He knows you regret them all, and He is a kind and loving G‑d.
And so, He delivers.
