The Life of Christ by Ven. Fulton Sheen - Ch. 60: Repentance

"The Angels of heaven, He said, rejoice more over one sinner doing penance than ninety-nine just who need not penance; the publican in the back of the temple mourning over his sins, He said, went back to his house justified. Now in His farewell discourse before the Ascension, He bade the world repent."
