[EinNYC]

If the Jew can pay for their own sin by their own work of repenting, why do they need the blood sacrifice?

In the days when the Temple stood, Jews were required to bring sacrifices to repent for sins as well as pray. Now that we don't have the Temple, we substitute personal repentance in prayer only.

Where in the Torah does it say that?

Thank you for replying!
