Repentance in Greek means something much closer to "thinking differently afterward" than it does "changing your cheating ways." Of course repentance can look like a prostitute becoming a librarian, but it can also look like a prostitute simply saying, "OK, I'm a sex worker and I don't know how to change that, but I can come here and receive bread and wine and I can hold onto the love of God without being deemed worthy of it by anyone but God.
