3306 – Even After Sin, One Can Become a Beinoni or Even a Tzaddik – אפילו לאחר חטא, אפשר להיות בינוני או אפילו צדיק

The Rebbe writes that even someone who has sinned and was once called wicked can still become a beinoni, or even a tzaddik. This is proven from Tanya and the teachings of our sages, showing that teshuvah is always effective and spiritual status can be transformed. https://www.torahrecordings.com/rebbe/igroskodesh/010/005/3306
