I've experience this first hand, and watched it from the other side. My mother is extremely "Christian", and that's one of her phrases there. To her, people helping her became an expectation, not an act of kindness. She was a single mom, and so people around town would help her out. Like our local appliance guy, he'd give her a deal on a new dishwasher - and then she would push her luck and ask him to install it. And then start calling him directly when the slightest thing might be wrong with it. And then for other appliances. And then for random handiman stuff. She of course never repaid him for everything he did.

Because he's a Christian, and so was she. So of course he was "happy" to do it for her. A few people eventually did tell her no, and she would immediately convince herself that they were bad people and that she "had to cut them out of her life" because of the negativity.
