The mitzvah of teshuvah

Hi,

A Jew is obligated to admit his sins before Gd when repenting from them. There is some debate as to whether teshuvah is actually a "mitzvah," but verbal admission is an essential part of the teshuvah process, and is considered a mitzvah in itself.

(Rambam, Mishneh Torah Hilchot Teshuvah 1:1)

Have a great day,
Mordechai
