By the way your mom describes depression, it’s obvious she doesn’t understand what it actually is. She likely thinks depressed people simply sleep all day and feel sad. I would start by asking her to define the terms she’s using, have her define depression and value, then ask what she believes laziness means. The way she frames this suggests she’s repeating something she heard rather than expressing a considered worldview. It probably isn’t her own position; she’s just agreeing with it. Ask her what she actually believes, assuming she has a coherent position at all. Finally, close the discussion by asking whether she has actually read the Bible from front to back. That question usually ends the conversation.
